<div>A '''conjugate''' is a sequence of moves that consists in doing a sequence A, then a sequence B, and finally the inverse of the sequence A. In other words, a conjugate is an algorithm like A B A', where A and B can be any sequence of moves. In intuitive terms, it means: do something to set up another task which does something useful, and undo the setup.<br />
<br />
== Mathematical definition ==<br />
<br />
Given a group, a '''conjugate''' is an element of the form <i>ghg'</i>, where <i>g</i> and <i>h</i> are elements of the group with inverses <i>g'</i> and <i>h'</i>.<br />
<br />
Cube notation is very close : A B A'<br />
<br />
It is sometimes written as [A: B] = A B A'<br />
<br />
== Effect ==<br />
<br />
In A B A', the sequence A is the setup move or sequence and A' puts the cube in its original state. In between, there is an embedded sequence B. Alone, this sequence would affect some set of locations '''K''' on the cube. Because of the conjugation, the affected pieces will be '''K'''A', which means that the locations will be transformed by the inverse of A.<br />
<br />
Indeed the sequence B will be applied on a cube which space has been modified by A. The sequence B is supposed to change some pieces in the locations '''K''' and A consists in bringing the piece you want to change to the location '''K'''. Once you've done the sequence B, you bring those pieces back with A'.<br />
<br />
=== Trivial case ===<br />
<br />
If the set of locations '''K''' is not modified by A, then the conjugation does not change anything, and A B A' = B.<br />
<br />
=== General case ===<br />
<br />
Pieces can be affected by the following subsequence of ABA':<br />
* by B only: this part is outside of the conjugation<br />
* by AB: this is the first semi-conjugated part<br />
* by BA': this is the second semi-conjugated part<br />
* by ABA': this is the conjugated part<br />
<br />
Let's call '''J''' the set of pieces modified by A, and '''N''' the intersection of '''J''' and '''K'''.<br />
<br />
The initial location of the outside part is:<br />
'''O''' = (('''K''' \ '''N''')B \ '''N''')B'<br />
<br />
The initial location of the first semi-conjugated part is:<br />
'''H'''<sub>1</sub> = ('''N'''B \ '''N''')B'A'<br />
<br />
The initial location of the second semi-conjugated part is:<br />
'''H'''<sub>2</sub> = '''N'''B' \ '''N'''<br />
<br />
The initial location of the conjugated part is:<br />
'''C''' = ('''N'''B inter '''N''')B'A'<br />
<br />
The slot location is:<br />
'''N'''A'<br />
<br />
=== Usage ===<br />
<br />
The conjugation is often used to provide a setup for some transformation. The conjugation ABA' is very similar to B, except that B is applied on other pieces as it would be without conjugation. For example, if a sequence exchange some pieces, or rotate some pieces, you can choose to exchange other pieces or rotate other pieces :<br />
<br />
[F': [M2D2M2, U]]<br />
<br />
where [M2D2M2, U] exchange the four top edges, so applying F' exchange the front-right edge instead of the front-top edge.<br />
<br />
The intersection is '''N''' = front-top edge<br />
<br />
The slot is '''N'''A' = '''N'''F = front-right edge<br />
<br />
The conjugated part is:<br />
<br />
'''C''' = ('''N'''B inter '''N''')B'A' = empty<br />
<br />
Surprisingly, in this example, the conjugated part is empty. It means that no individual piece is actually following the whole conjugation. F' and [M2D2M2, U] are only connected so that some pieces are transfered through the intersection '''N'''. The transfer occur between both semi-conjugated parts.<br />
<br />
In this simple case, we do not really distinguish the semi-conjugated parts. But it is possible to take this difference into account, and also to use a conjugated part.<br />
<br />
==== Semi-conjugated parts ====<br />
<br />
Semi-conjugated parts can be used to move pieces inside or outside a slot. This is widely used to insert or extract a pair of pieces in [[F2L]] or to insert or extract corners or edges individually. <br />
<br />
'''H'''<sub>1</sub> is extracted from the slot and '''H'''<sub>2</sub> is inserted into the slot.<br />
<br />
Example: RU'R'<br />
<br />
'''N''' = top-right edge, top-right-back and top-right-front corners<br />
<br />
Slot location : '''N'''A' = '''N'''R' = top-right-front corner, front-right edge and front-right-bottom corner<br />
<br />
'''H'''<sub>1</sub> = ('''N'''U' \ '''N''')UR' = top-right-front corner and front-right edge<br />
<br />
These pieces are extracted from the slot and replace the top-back edge and top-back-left corner.<br />
<br />
'''H'''<sub>2</sub> = '''N'''U \ '''N''' = top-front-right corner and top-front edge<br />
<br />
These pieces are inserted into the slot, replacing front-right edge, and front-right-bottom corner.<br />
<br />
Example: RUR'<br />
<br />
'''N''' = top-right edge, top-right-back and top-right-front corners<br />
<br />
Slot location : '''N'''A' = '''N'''R' = top-right-front corner, front-right edge and front-right-bottom corner<br />
<br />
'''H'''<sub>1</sub> = ('''N'''U \ '''N''')U'R' = front-right edge and front-right-bottom corner<br />
<br />
These pieces are extracted from the slot and replace the top-front edge and top-front-left corner.<br />
<br />
'''H'''<sub>2</sub> = '''N'''U' \ '''N''' = top-back-left corner and top-back edge<br />
<br />
These pieces are inserted into the slot, replacing front-right edge, and front-right-top corner.<br />
<br />
==== Conjugated part ====<br />
<br />
The conjugated part is used to move pieces inside the slot (the pieces do not enter nor leave the slot):<br />
<br />
RUR'<br />
<br />
where the intersection is '''N''' = top-right edge, top-right-front corner and top-right-back corner<br />
<br />
and the slot is '''N'''A' = '''N'''R' = front-right edge, front-right-top corner and front-right-bottom corner<br />
<br />
The conjugated part is :<br />
<br />
'''C''' = ('''N'''B inter '''N''')B'A' = top-right-front corner<br />
<br />
This piece is moved to the front-right-bottom corner and rotated so that the right facelet is moved to the bottom facelet.<br />
<br />
=== Link with commutators ===<br />
<br />
The outside part '''O''' is only affected by B', so it can be put back into place by adding B' to the sequence, giving ABA'B', which is the [[commutator]] of A and B. <br />
<br />
The first semi-conjugated part '''H'''<sub>1</sub>, which was affected by AB, is then only affected by A, becoming the container of pieces P<sub>A</sub>. <br />
<br />
The second semi-conjugated part '''H'''<sub>2</sub> is split into two parts:<br />
* one part which is affected by B', so affected by BA'B', and is then a conjugated part of the commutator<br />
* one part which is not affected by B', so affected only by BA', becoming the container of pieces P<sub>B</sub>.<br />
<br />
The conjugated part is split into two parts:<br />
* one part which is affected by B', becoming the quirk part<br />
* one part which is not, becoming a conjugated part of the commutator<br />
<br />
Pieces that were not affected by the conjugate, but that are affected by the last B' move, are the P<sub>N</sub> pieces of the corresponding commutator.<br />
<br />
== Differences among conjugation, transformation, and pseudo/non-matching blocks ==<br />
<br />
As of August 2020, it seems that the terminology has been used interchangeably recently.<br />
<br />
=== Conjugation ===<br />
<br />
Conjugation is very broad. This is the general term for A B A'. You perform a setup, do some moves, then undo the setup. You have performed a setup so that you can easily perform the moves in "B". The A setup moves cause the puzzle to be in an offset state, changing the appearance. Then you undo the offset later. However, traditionally there is no further intent within this setup move. It wasn't until around 10 years ago that the technique of [[offsett]]ing a layer was applied with the intent to reduce large algorithm sets and the overall move count of a method. That is where the term [[Transformation]] comes in. It refers to this specific technique.<br />
<br />
=== Transformation ===<br />
<br />
{{Main Article|Article=Transformation}}<br />
Transformation is the application of a conjugate to change the state of the cube to gain a large advantage in the future. This is a relatively new term in the community. Transformation technically is conjugation, but there is a big difference in the intent. The reason for the application is completely different from the traditional use of A B A' setup, moves, setup undo. In transformation you are intentionally trying to change a [[case]] into another. You are taking advantage of the state of the pieces to improve the rest of the solve. Transformation is used to reduce the number of [[move]]s and the number of [[case]]s in a method. Conjugation doesn't specifically refer to this intent; it is a general term. Transformation is a different technique under the conjugation umbrella.<br />
<br />
[[Image:Transformation1.png|120px|link=Sune]]<br />
Setup = L' U R U' L U R' U'. This is one of the [[Sune]] orientation cases. But if you use the URF+UR pair and do an R' turn, you get the below state.<br />
<br />
[[Image:Transformation2.png|120px]]<br />
You have now transformed a [[Sune]] case into an L case. This is the L case solved by r U R U' L' U R' U'. So if you do r U R U' L' U R' U' then R (which undoes the R' turn in the last example), it will be solved.<br />
<br />
Example methods/applications: [[NMLL]], [[A2]], [[CTLS]], [[42]], and other case reduction applications.<br />
<br />
=== Pseudo/Non-Matching ===<br />
<br />
{{Main Article|Article=Pseudoblocks}}<br />
This is when pieces are put together in such a way that the colors don't match. This is referring to the building process. We are only talking about the current state of the pieces. It is all about what everything looks like right now - not about your future intent.<br />
<br />
[[Image:Roux_NM.png|120px|link=Roux]]<br />
[[Image:ZZ_NM.png|120px|link=ZZ]]<br />
<br />
<br />
Example methods/applications: [[Roux]], [[Heise]], [[ZZ]], [[FMC]], [[A2]], [[A3]], and it can be used in pretty much everything else.<br />
<br />
=== Differences among conjugation, transformation, and pseudo/non-matching blocks ===<br />
<br />
In summary, the difference is in intent. In language, we have many separate words to clarify intention and reason. It is important to understand the differences for clarity. When someone says "conjugated Roux" or "conjugated ZBLL", it isn't clear what is meant and it requires them to provide an explanation. Do they mean Roux/ZZ with non-matching blocks? For Roux, do they mean 42? For ZZ, do they mean CTLS? Or do they mean something else? Because pseudo/non-matching and transformation fall under conjugation, it is important to use the correct term for the specific technique that is being used.<br />

|NAME=15 puzzle<br />
|IMAGE=<br />
|ALTERNATIVENAMES=16 puzzle, Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square. 15 Klotski Puzzle<br />
|SHAPE=Square<br />
|MECHANISM=None<br />

|YEAR=1874<br />
|COMPANIES=[[QiYi]]<br />
|JAAPSCH=fifteen}}<br />
<br />
The '''15 puzzle''' is a sliding puzzle made out of 15 numbered square pieces in a 4x4 grid, with one empty spot which allows for moving the pieces around. The objective is to solve the puzzle by bringing the pieces with numbers on them in the correct order. Instead of numbers, images are sometimes used as well.<br />
<br />
== Notation ==<br />
Due to the puzzle's properties, 15 puzzle notation is quite easy and intuitive.<br />
<br />
There are four basic types of moves: U, R, D and L, referring to Up, Right, Down and Left, respectively. The moves describe the movement of the pieces, not the empty spot. That means that when a piece moves to the right and the empty spot moves to the left, this is referred to as R. When more than one of the same move is done in a row, the number of moves is appended instead of writing out the move that many times. E.g. when R is performed twice, this is referred to as R2.<br />
<br />
== Methods ==<br />
Lots of different approaches to solving the 15 puzzle exist, some of which are listed here.<br />
<br />
=== LBL ===<br />
Layer by layer (sometimes also called Rows) is one of easiest methods to come up with and therefore most commonly used among non-speedsolvers. The puzzle is done layer by layer or in rows for most of the solve. The steps are the following:<br />
# Solve one row.<br />
## Solve the two upper-left pieces.<br />
## Place one of the last two pieces in the correct layer but wrong position.<br />
## Place the other piece on top.<br />
## Solve the first piece using L or R.<br />
## Solve the second piece using U.<br />
# Solve another row.<br />
# Solve the two left-most pieces (similar to solving the last two pieces of one layer, but vertically).<br />
# Solve the next two left-most pieces.<br />
# Solve the remaining three pieces intuitively.<br />
<br />
For solving the last two pieces of a layer, one can alternatively also solve the piece that touches one of the other two pieces (i.e. not the one that belongs in the corner), move the first piece of the layer out of the way, move the other three pieces (including the random edge) in its place, move the unsolved edge up so it becomes solved, take the random edge out of the layer and resolve the second, third and first piece.<br />
<br />
=== Fringe ===<br />
The fringe method is a method for speedsolving the 15 puzzle and roughly similar to LBL in speed. It solves the puzzle by solving the fringes of the puzzle, gradually reducing it to smaller puzzles until the puzzle is solved.<br />
<br />
# Solve the top and left row to reduce the puzzle to an 8 puzzle.<br />
# Repeat again to reduce to a 3 puzzle.<br />
# Solve the remaining three pieces intuitively.<br />

''This page is about the [[Gear Cube]] puzzle. For the Gear Cube Extreme or the Anisotropic Gear Cube, see [[Gear Cube Extreme]]. For a list of geared puzzles, see [[:Category:Geared puzzles]].''<br />
<br />
The '''Gear Cube''' (also known as the '''Caution Cube''') is a twistable [[puzzle]] in the shape of a [[cube]] that is cut two times along each of three axes, as a [[3x3x3]]. Moreover, there are geared [[edge]]s. That means the edges can turn around themselves. It was invented by [[Oskar van Deventer]] (idea of [[Bram Cohen]]). It was first produced by [[Shapeways]] since 2009, and then by [[Meffert's]] since 2010 (for 36€) and it finally got copied by [[LanLan]].<br />
<br />
This puzzle has 6 fixed [[center]]s (they can't move related to each others), 12 [[edge]]s, and 8 [[corner]]s, and a total of 41,472 positions. It has been proven that every position can be solved in 8 or fewer moves in [[ATM]] and 12 or fewer in [[HTM]]. It's important to note that quarter moves block the cube (only half turns are unprohibited) so [[QTM]] has no meaning for this puzzle.<br />
<br />
It's not an official event in WCA competition.<br />
<br />
The current unofficial [[world record]] single speed solve is 2.16 seconds held by [[Kentaro Nishi]]. It looks harder but it is actually way easier to solve as compared as with a normal [[3x3x3]] cube.<br />

<br />
The '''Skewb''' (originally named the '''Pyraminx Cube''') is a twistable [[puzzle]] in the shape of a cube that is cut diagonally 2 times along each of 4 axes. It is a cube-shaped puzzle. It consists of 6 [[center]] pieces and 8 [[corner]] pieces (four of which are attached to the central core). Unlike the [[Rubik's cube]], which turns around faces, the Skewb turns around axes that go through its corners. It is a [[deep-cut]] puzzle - ie. each cut goes through the absolute center of the puzzle, and exactly half of the puzzle changes with each turn.<br />
<br />
This puzzle was originally called the Pyraminx Cube by [[Uwe Meffert]], but Douglas Hofstadter suggested the name "Skewb", and it has been called that ever since.<br />

The '''Square-1''' (short for '''Back to Square One''', also known as '''Cube 21''') is a cubic twisty [[puzzle]], with irregular [[cubie]]s. It's one of the most popular [[shape-shift]]ing [[Rubik's Cube variant]]s.<br />
<br />
== Description ==<br />
<br />
It has only 2 axes of rotation (the top/bottom faces and the entire right/left half of the puzzle).<br />
The puzzle consists of two halves, each with [[corner]] and [[edge]] pieces indistinguishable to the [[core]]. That means that corners can be swapped with edges and otherwise.<br />
The top and bottom [[layer]]s consist of triangular edge pieces and quadrilateral corner pieces. The middle layer consists of two trapezoidal pieces. When scrambled, it shifts to a random shape : it's a [[shape-shifting twisty puzzle]].<br />
There are 552,738,816,000 positions (170 × 2 × 8! × 8!).<br />
<br />
=== Goal ===<br />
The goal is to return the cube to its cubic state with each side one solid color.<br />
For the silver variation, the goal is only to return the cube to its cubic state.<br />
<br />

<br />
== Square-1 Notation ==<br />
{{Main Article|Article=Square-1 notation}}<br />
Square-1 Notation refers to the description of what symbols indicate what [[move]]s to apply on a square-1.<br />
<br />
The original Square-1 notation, created by [[Jaap Scherphuis]], uses moves of the form (x,y) and moves of the form /. In an (x,y) twist, ''x'' indicates the number of 30-degree increments that the top layer should be twisted clockwise (an edge is 30 degrees and a corner is 60 degrees), and ''y'' indicates the number of 30-degree increments that the bottom should be twisted clockwise. A / twist simply refers to turning the entire right half of the puzzle by 180 degrees.<br />
<br />
It is important to note that in this notation the puzzle must be held so that the layers containing the corners and edges are on the top and bottom, and the middle layer should be in a position so that, on the front side, the shorter middle-layer [[sticker]] should be on the left. Thus, from a solved state, the turn (1,-1)/ is possible, but (-1,1)/ is not.<br />
<br />
In the newer official notation, adopted by the WCA, there is no /. The WCA regulations (version 2008 v1) say: "(x,y) means: turn upper layer x stickers clockwise, turn bottom layer y stickers clockwise, turn right half of the puzzle 180 degrees. Stickers are counted on the outside of the upper slice." Thus, every (x,y) move is considered to be followed by a / move.<br />
<br />
[[Mike Masonjones]] proved in 2005 God's Number for the Square-1 to be equal 13 (in the twist metric). That means the puzzle can be solved in 13 twists or less. (12 if the middle layer is ignored).<br />
<br />
== Methods ==<br />
{{Main Article|Article=Square-1 methods}}<br />
The puzzle is much easier to work with when it is in the shape of a cube so generally the first step is to somehow (there are several methods) get the pieces arranged so that the puzzle is cubic. Then, the pieces are separated into their correct layers, and permuted. Note that there is no possible incorrect orientation for pieces, since the middle layer can only rotate through 180 degrees at a time (many talks about separation as "orientation").<br />

The '''6x6x6 cube''' (normally referred to as the '''6x6x6''' or '''6x6''') is a twistable [[puzzle]] in the shape of a cube that is cut five times along each of three axes. The only available brand for this puzzle was the [[V-Cube]], which was patented by [[Panagiotis Verdes]]. The V-Cube 6x6 incorporates a clicking mechanism designed to keep the hidden middle layer in alignment with the rest of the pieces. Several mods have been developed to fix this, most notably the MeMyselfandPi 6x6 mod, which involves eliminating the clicking mechanism and using pins instead to keep the inner middle layer in alignment. Shengshou released their 6x6x6 in mid-2011. Other 6x6x6 cubes have since been released by [[Moyu]], [[QiYi]], and [[YuXin]]. Most 6x6x6 cubes developed after the V-Cube use an internal alignment mechanism and do not have a clicking mechanism.<br />

The '''7x7x7 cube''' (normally referred to as the '''7x7x7''' or '''7x7''') is a twistable [[puzzle]] in the shape of a cube that is cut six times along each of three axes. The first brand of this puzzle was the [[V-Cube 7]], which was patented by its inventor, [[Panagiotis Verdes]]. Early on, many other cube companies produced puzzles very similar, but these were considered [[knock-off]]s due to using the same basic mechanism. The V Cube 7 is rounded (or 'pillowed'), while most subsequent 7x7s are cubic.<br />
<br />
[[Shengshou]] have made a cubic 7x7, and it has become very popular, particularly the smaller version. [[MoYu]] have also made a 7x7 called the AoFu, which has a pillowed shape like the V-Cube 7. Moyu has since released a cubic version of the AoFu, called the Cubic AoFu GT. Later, [[MoFang JiaoShi]] released the first [[budget cubes | budget]] 7x7, the MF7S. Shortly after, QiYi released the WuJi 7x7, and YJ released the GuanFu 7x7 and the YuFu 7x7.<br />

The '''5x5x5 cube''' (also known as the '''Professor's Cube''', and normally referred to as the '''5x5x5''' or '''5x5''') is a twistable [[puzzle]] in the shape of a cube that is cut four times along each of three axes. <br />
<br />
The 5x5x5 cube was invented by [[Udo Krell]] in 1981. Several designs for the 5x5x5 were proposed at the time, but it was Krell's design which was first manufactured (by [[Uwe Mèffert]]) in Hong Kong in 1983.[https://www.jaapsch.net/puzzles/cubic7.htm] It was marketed by [[Ideal Toys]] in Germany as "Rubik's Wahn" (Wahn = delusion or illusion). They were also sold in Japan under the name "Professor's Cube".[https://www.jaapsch.net/puzzles/cubic7.htm] In the 1990s Meffert reissued the "Professor's Cube".[http://helm.lu/cube/cube-lovers/txt-files/cube-mail-25.txt] In 1999 [[Chen Sen Li]] patented his [[East Sheen]] 5x5x5 cube. In 2004 [[Panagiotis Verdes]] filed a patent for big cubes which provided an improved mechanism for the 5x5x5 cube which he produced as part of the [[V-cube]] range. Since 2010 many Chinese companies beginning with [[Shengshou]] have released their own 5x5x5 cubes.<br />

<br />
The '''Rubik's cube''' (also known as the '''3x3x3 cube''', and normally referred to in the cubing community as the '''3x3x3''' or '''3x3''') is a twistable [[puzzle]] in the shape of a cube that is cut two times along each of three axes. It is said to be the best-selling toy in history, with well over 300 million cubes sold, and because of this popularity it is the most commonly practiced cube in [[speedsolving]]. The most popular brand is [[Rubik's Brand Cube]], which was first patented by [[Erno Rubik]] in 1975, and which began being produced on a wide scale in the early 1980s. From around 2007 the cubing community has seen the development of speedcubes made in China that have made significant improvements on Rubik's design.<br />

The '''4x4x4 Cube''' (also known as '''Rubik's Revenge''', and normally referred to as the '''4x4x4''' or '''4x4''') is a twisty [[puzzle]] in the shape of a cube that is cut three times along each of three axes. <br />
<br />
The 4x4x4 Cube was invented by [[Péter Sebestény]] in 1981 and sold under the name "Rubik's Revenge". In the 1990s they weren't being produced. As late as 1999 [[Meffert's]] puzzle website was telling its customers that "the 4x4x4 cube went out of production about 10 years ago, and cube collectors all over the world are now scrambling to get hold of any they see for sale".[https://web.archive.org/web/19990821041245/http://ue.net/mefferts-puzzles/profcube.html] However in 1998 [[Chen Sen Li]] patented a new mechanism for his [[East Sheen]] 4x4x4 cube (released c. 2003). In 2000 [[Meffert's]] started selling a "Master Cube" which was a copy of the old [[Rubik's]] mechanism.[https://web.archive.org/web/20000902052452/http://www.mefferts.com/mefferts-puzzles/new_lines.html] Similarly [[Rubik's]] began re-releasing a Rubik's Revenge in late 2000.[https://web.archive.org/web/20001217103300/http://www.rubiks.com/revenge.html] Since around 2010 other brands have appeared beginning with the [[Shengshou]], [[Dayan]], and [[MF8]] cubes.<br />
<br />
The 4x4x4 Cube has no fixed centers, but a total of 24 [[center]] pieces, a total of 24 [[edge]] pieces, and 8 [[corner]]s. It has 7.4 x 10<sup>45</sup> positions.<br />

The '''Pyraminx''' is a triangular pyramid-shaped (or tetrahedron) [[puzzle]]. The parts are arranged in a pyramidal pattern on each side of the puzzle. The layers can be rotated with respect to each vertex, and the individual tips can be rotated as well. It was designed by [[Uwe Mèffert]] in the early 1970s.<br />
<br />
In the early 1970s Uwe Mèffert experimented with slicing polyhedra into symmetric slices and attaching them with rubber bands to a center ball. His wooden puzzles eventually end up in a drawer half-forgotten. It was only when the [[Rubik's Cube]] craze hit in the early 1980s that Mèffert brought it to the attention of a toy company. Over 10 million pyraminxes were sold by Christmas 1981, and 90 million within 3 years. <br />
<br />
The pyraminx is a tetrahedron trisected by planes parallel to each face. This means there are 4 axial pieces, 6 edge pieces, and 4 tips. The pyraminx can be arranged into 75,582,720 possible positions. This sounds a lot compared with the [[2x2x2 Cube]] which has 3,674,160 possible positions. However, solving the tips is trivial, and ignoring these reduces the possibilities to 933,120 positions. In addition, the axial pieces can be easily rotated so that their colors line up with each other, reducing the problem to just the six edge pieces with 11,520 possible positions. This makes the pyraminx one of the simplest of the twisty puzzles.<br />
<br />
==Variants==<br />
*'''Tetraminx'''. The simplest variant is the [[Tetraminx]] which is equivalent to the Pyraminx but without the tips.<br />
*'''Master Pyraminx'''. The [[Master Pyraminx]] is a 4-layer pyraminx with 16 triangles per face. It has about 2.17225 × 10<sup>17</sup> possible combinations.<br />
*'''Professor Pyraminx'''. The [[Professor Pyraminx]] is a 5-layer pyraminx with 25 triangles per face.<br />
*'''Royal Pyraminx'''. The [[Royal Pyraminx]] is a 6-layer pyraminx with 36 triangles per face.<br />
*'''Emperor Pyraminx'''. The [[Emperor Pyraminx]] is a 7-layer pyraminx with 49 triangles per face.<br />

The '''2x2x2 Cube''' (also known as a '''Pocket Cube''' or '''Mini Cube''' and normally referred to as the '''2x2x2''' or '''2x2''') is a twistable [[puzzle]] in the shape of a [[cube]] that is cut once along each of three axes. <br />
<br />
The first such cube was [[Rubik's Brand|Rubik's Pocket Cube]] invented by [[Erno Rubik]] and released by [[Ideal]] Toys in 1981. In 1998 [[Chen Sen Li]] patented his [[East Sheen]] cube. Since the mid-2000s other brands began to appear such as the [[LanLan]], the [[Ghosthand 2x2x2|Ghosthand]] and the [[WitTwo]]. <br />
<br />
This puzzle has 8 [[corner]] pieces only. The 2x2x2 cube has 3,674,160 possible positions (assuming one piece is always solved from orienting the puzzle), each of which can be solved in 11 turns ([[HTM]]) / 14 turns ([[QTM]]) or fewer.<br />

The '''Dino Cube''' is a three-layered [[twisty puzzle]] in which three edge pieces at the corners are moved at a time.<br />
<br />
== History ==<br />
The first functional Dino Cube was invented in 1985 by [[Robert Webb]] of Australia, made out of paper. [[Stephen Harvey]] also produced a <br />
prototype independent of Webb in 1990. However, the Dino Cube was not mass produced until 1995 by [[S.Y. Liou]], convinced by [[Liang-Yen Wu]]. The first mass-produced Dino Cube included 2-color, 4-color, and 6-color options to choose from.<br />
<br />
In 1998, [[James R. Holloway]] applied for a patent for the Dino Cube and was granted the patent in 2000, filed as patent US6056290.<br />

<br />
The '''Redi Cube''' is a three-layered [[twisty puzzle]] on which each corner turn moves the three edges around it.<br />
<br />
The Redi Cube was designed by [[Oskar van Deventer]] in 2009 and released by [[MoYu]] in early June 2017. The Redi Cube is based on the [[Dino Cube]], the difference being the Redi Cube has corner pieces. There are some people trying to get the cube into the [[WCA]], but nothing has happened yet. It is solved very similarly to the [[Pyraminx]] using edge-swapping commutators.<br />
<br />
== Variants ==<br />
=== Dino Cube ===<br />
The [[Dino Cube]] is a 2x2 version of the Redi Cube with only the edges. It is extremely easy to solve compared to most other shape-preserving cubes, however, it is not trivial and can be confusing at first.<br />
=== Fadi Cube ===<br />
Also known as the Mosaic Cube, the Fadi Cube is a 4x4 [[Bubbloid]] / Redi Cube type puzzle. With four different layers per axis, it can be turned as a Redi cube by only turning the outermost turnable layers, as much like the Redi Cube, the outermost layer is not turnable. It solves similarly to a Master Pyraminx.<br />
<br />
=== Compy Cube ===<br />
The Compy Cube is similar to the Redi Cube, using a Dino Cube mechanism. It solves similarly to the Redi Cube.<br />
=== Master Compy Cube ===<br />
The master Compy a Cube is a Compy Cube with an extra layer.<br />

''This page is about the [[Gear Cube]] puzzle. For the Gear Cube Extreme or the Anisotropic Gear Cube, see [[Gear Cube Extreme]]. For a list of geared puzzles, see [[:Category:Geared puzzles]].''<br />
<br />
The '''Gear Cube''' (also known as the '''Caution Cube''') is a twistable [[puzzle]] in the shape of a [[cube]] that is cut two times along each of three axes, as a [[3x3x3]]. Moreover, there are geared [[edge]]s. That means the edges can turn around themselves. It was invented by [[Oskar van Deventer]] (idea of [[Bram Cohen]]). It was first produced by [[Shapeways]] since 2009, and then by [[Meffert's]] since 2010 (for 36€) and it finally got copied by [[LanLan]].<br />
<br />
This puzzle has 6 fixed [[center]]s (they can't move related to each others), 12 [[edge]]s, and 8 [[corner]]s, and a total of 41,472 positions. It has been proven that every position can be solved in 8 or fewer moves in [[ATM]] and 12 or fewer in [[HTM]]. It's important to note that quarter moves block the cube (only half turns are unprohibited) so [[QTM]] has no meaning for this puzzle.<br />
<br />
It's not an official event in WCA competition.<br />
<br />
The current unofficial [[world record]] single speed solve is 2.16 seconds held by [[Kentaro Nishi]]. It looks harder but it is actually way easier to solve as compared as with a normal [[3x3x3]] cube.<br />
<br />

<br />
The '''Square-1''' (short for '''Back to Square One''', also known as '''Cube 21''') is a cubic twisty [[puzzle]], with irregular [[cubie]]s. It's one of the most popular [[shape-shift]]ing [[Rubik's Cube variant]]s.<br />
<br />
== Description ==<br />
<br />
It has only 2 axes of rotation (the top/bottom faces and the entire right/left half of the puzzle).<br />
The puzzle consists of two halves, each with [[corner]] and [[edge]] pieces indistinguishable to the [[core]]. That means that corners can be swapped with edges and otherwise.<br />
The top and bottom [[layer]]s consist of triangular edge pieces and quadrilateral corner pieces. The middle layer consists of two trapezoidal pieces. When scrambled, it shifts to a random shape : it's a [[shape-shifting twisty puzzle]].<br />
There are 552,738,816,000 positions (170 × 2 × 8! × 8!).<br />
<br />
=== Goal ===<br />
The goal is to return the cube to its cubic state with each side one solid color.<br />
For the silver variation, the goal is only to return the cube to its cubic state.<br />
<br />

<br />
== Square-1 Notation ==<br />
{{Main Article|Article=Square-1 notation}}<br />
Square-1 Notation refers to the description of what symbols indicate what [[move]]s to apply on a square-1.<br />
<br />
The original Square-1 notation, created by [[Jaap Scherphuis]], uses moves of the form (x,y) and moves of the form /. In an (x,y) twist, ''x'' indicates the number of 30-degree increments that the top layer should be twisted clockwise (an edge is 30 degrees and a corner is 60 degrees), and ''y'' indicates the number of 30-degree increments that the bottom should be twisted clockwise. A / twist simply refers to turning the entire right half of the puzzle by 180 degrees.<br />
<br />
It is important to note that in this notation the puzzle must be held so that the layers containing the corners and edges are on the top and bottom, and the middle layer should be in a position so that, on the front side, the shorter middle-layer [[sticker]] should be on the left. Thus, from a solved state, the turn (1,-1)/ is possible, but (-1,1)/ is not.<br />
<br />
In the newer official notation, adopted by the WCA, there is no /. The WCA regulations (version 2008 v1) say: "(x,y) means: turn upper layer x stickers clockwise, turn bottom layer y stickers clockwise, turn right half of the puzzle 180 degrees. Stickers are counted on the outside of the upper slice." Thus, every (x,y) move is considered to be followed by a / move.<br />
<br />
[[Mike Masonjones]] proved in 2005 God's Number for the Square-1 to be equal 13 (in the twist metric). That means the puzzle can be solved in 13 twists or less. (12 if the middle layer is ignored).<br />
<br />
== Methods ==<br />
{{Main Article|Article=Square-1 methods}}<br />
The puzzle is much easier to work with when it is in the shape of a cube so generally the first step is to somehow (there are several methods) get the pieces arranged so that the puzzle is cubic. Then, the pieces are separated into their correct layers, and permuted. Note that there is no possible incorrect orientation for pieces, since the middle layer can only rotate through 180 degrees at a time (many talks about separation as "orientation").<br />

The '''Skewb''' (originally named the '''Pyraminx Cube''') is a twistable [[puzzle]] in the shape of a cube that is cut diagonally 2 times along each of 4 axes. It is a cube-shaped puzzle. It consists of 6 [[center]] pieces and 8 [[corner]] pieces (four of which are attached to the central core). Unlike the [[Rubik's cube]], which turns around faces, the Skewb turns around axes that go through its corners. It is a [[deep-cut]] puzzle - ie. each cut goes through the absolute center of the puzzle, and exactly half of the puzzle changes with each turn.<br />
<br />
This puzzle was originally called the Pyraminx Cube by [[Uwe Meffert]], but Douglas Hofstadter suggested the name "Skewb", and it has been called that ever since.<br />

<br />
The '''Rubik's cube''' (also known as the '''3x3x3 cube''', and normally referred to in the cubing community as the '''3x3x3''' or '''3x3''') is a twistable [[puzzle]] in the shape of a cube that is cut two times along each of three axes. It is said to be the best-selling toy in history, with well over 300 million cubes sold, and because of this popularity it is the most commonly practiced cube in [[speedsolving]]. The most popular brand is [[Rubik's Brand Cube]], which was first patented by [[Erno Rubik]] in 1975, and which began being produced on a wide scale in the early 1980s. From around 2007 the cubing community has seen the development of speedcubes made in China that have made significant improvements on Rubik's design.<br />
<br />
This puzzle has 6 fixed [[center]]s, 12 [[edge]]s, and 8 [[corner]]s, and a total of 43,252,003,274,489,856,000 (or =~ 4.3 x 10^19) positions. It has been proven that every position can be solved in 20 or fewer moves (https://cube20.org/).<br />

The '''7x7x7 cube''' (normally referred to as the '''7x7x7''' or '''7x7''') is a twistable [[puzzle]] in the shape of a cube that is cut six times along each of three axes. The first brand of this puzzle was the [[V-Cube 7]], which was patented by its inventor, [[Panagiotis Verdes]]. Early on, many other cube companies produced puzzles very similar, but these were considered [[knock-off]]s due to using the same basic mechanism. The V Cube 7 is rounded (or 'pillowed'), while most subsequent 7x7s are cubic.<br />
<br />
[[Shengshou]] have made a cubic 7x7, and it has become very popular, particularly the smaller version. [[MoYu]] have also made a 7x7 called the AoFu, which has a pillowed shape like the V-Cube 7. Moyu has since released a cubic version of the AoFu, called the Cubic AoFu GT. Later, [[MoFang JiaoShi]] released the first [[budget cubes | budget]] 7x7, the MF7S. Shortly after, QiYi released the WuJi 7x7, and YJ released the GuanFu 7x7 and the YuFu 7x7.<br />
<br />
This puzzle has 6 fixed [[center]]s, a total of 144 other [[center]] pieces, a total of 60 [[edge]] pieces, and 8 [[corner]]s, and has 2.0 * 10^160 positions.<br />

The '''5x5x5 cube''' (also known as the '''Professor's Cube''', and normally referred to as the '''5x5x5''' or '''5x5''') is a twistable [[puzzle]] in the shape of a cube that is cut four times along each of three axes. <br />
<br />
The 5x5x5 cube was invented by [[Udo Krell]] in 1981. Several designs for the 5x5x5 were proposed at the time, but it was Krell's design which was first manufactured (by [[Uwe Mèffert]]) in Hong Kong in 1983.[https://www.jaapsch.net/puzzles/cubic7.htm] It was marketed by [[Ideal Toys]] in Germany as "Rubik's Wahn" (Wahn = delusion or illusion). They were also sold in Japan under the name "Professor's Cube".[https://www.jaapsch.net/puzzles/cubic7.htm] In the 1990s Meffert reissued the "Professor's Cube".[http://helm.lu/cube/cube-lovers/txt-files/cube-mail-25.txt] In 1999 [[Chen Sen Li]] patented his [[East Sheen]] 5x5x5 cube. In 2004 [[Panagiotis Verdes]] filed a patent for big cubes which provided an improved mechanism for the 5x5x5 cube which he produced as part of the [[V-cube]] range. Since 2010 many Chinese companies beginning with [[Shengshou]] have released their own 5x5x5 cubes.<br />
<br />
This puzzle has 6 fixed [[center]]s, a total of 48 other [[center]] pieces, a total of 36 [[edge]] pieces, and 8 [[corner]]s, and 2.8 x 10^74 positions.<br />

The '''4x4x4 Cube''' (also known as '''Rubik's Revenge''', and normally referred to as the '''4x4x4''' or '''4x4''') is a twisty [[puzzle]] in the shape of a cube that is cut three times along each of three axes. <br />
<br />
The 4x4x4 Cube was invented by [[Péter Sebestény]] in 1981 and sold under the name "Rubik's Revenge". In the 1990s they weren't being produced. As late as 1999 [[Meffert's]] puzzle website was telling its customers that "the 4x4x4 cube went out of production about 10 years ago, and cube collectors all over the world are now scrambling to get hold of any they see for sale".[https://web.archive.org/web/19990821041245/http://ue.net/mefferts-puzzles/profcube.html] However in 1998 [[Chen Sen Li]] patented a new mechanism for his [[East Sheen]] 4x4x4 cube (released c. 2003). In 2000 [[Meffert's]] started selling a "Master Cube" which was a copy of the old [[Rubik's]] mechanism.[https://web.archive.org/web/20000902052452/http://www.mefferts.com/mefferts-puzzles/new_lines.html] Similarly [[Rubik's]] began re-releasing a Rubik's Revenge in late 2000.[https://web.archive.org/web/20001217103300/http://www.rubiks.com/revenge.html] Since around 2010 other brands have appeared beginning with the [[Shengshou]], [[Dayan]], and [[MF8]] cubes.<br />
<br />
The 4x4x4 Cube has no fixed centers, but a total of 24 [[center]] pieces, a total of 24 [[edge]] pieces, and 8 [[corner]]s. It has 7.4 x 10<sup>45</sup> positions.<br />

[[Image:pyraminx.jpg|250px|thumb|right|Mefferts Original Pryaminx]]<br />
The '''Pyraminx''' is a triangular pyramid-shaped (or tetrahedron) [[puzzle]]. The parts are arranged in a pyramidal pattern on each side of the puzzle. The layers can be rotated with respect to each vertex, and the individual tips can be rotated as well. It was designed by [[Uwe Mèffert]] in the early 1970s.<br />
<br />
In the early 1970s Uwe Mèffert experimented with slicing polyhedra into symmetric slices and attaching them with rubber bands to a center ball. His wooden puzzles eventually end up in a drawer half-forgotten. It was only when the [[Rubik's Cube]] craze hit in the early 1980s that Mèffert brought it to the attention of a toy company. Over 10 million pyraminxes were sold by Christmas 1981, and 90 million within 3 years. <br />
<br />
The pyraminx is a tetrahedron trisected by planes parallel to each face. This means there are 4 axial pieces, 6 edge pieces, and 4 tips. The pyraminx can be arranged into 75,582,720 possible positions. This sounds a lot compared with the [[2x2x2 Cube]] which has 3,674,160 possible positions. However, solving the tips is trivial, and ignoring these reduces the possibilities to 933,120 positions. In addition, the axial pieces can be easily rotated so that their colors line up with each other, reducing the problem to just the six edge pieces with 11,520 possible positions. This makes the pyraminx one of the simplest of the twisty puzzles.<br />
<br />
==Variants==<br />
*'''Tetraminx'''. The simplest variant is the [[Tetraminx]] which is equivalent to the Pyraminx but without the tips.<br />
*'''Master Pyraminx'''. The [[Master Pyraminx]] is a 4-layer pyraminx with 16 triangles per face. It has about 2.17225 × 10<sup>17</sup> possible combinations.<br />

<br />
Today's featured article is '''[[Last Layer]]'''.<br />
<br />
<br />
The term [[last layer]] (normally abbrevated as LL, also called Last Slice) refers to the complete movable "layer" of a [[twisty puzzle]] which is the last to be solved in a [[Layer-By-Layer]]-related method. The last layer is the layer that must be solved on a [[cube]] when all of the other layers have already been finished. All pieces of the last layer can move together.<br />
<br />
Last layer is different from a last [[face]]: Rather than just including the stickers of the last side of a twisty puzzle, the last layer includes all of the stickers on all of the pieces of the last slice.<br />

<br />
[[Feliks Zemdegs]] is an Australian speedcuber from Melbourne, Australia. He is widely considered to be the most successful competitive cuber in history, being the first ever to hold over one hundred [[world records]] since the start of his cubing career. Only recently have other people begun to catch up, with [[Max Park]] being the first to (briefly) break Felik's 7-year streak of holding the world record [[average]] for the [[Rubik's cube]] in 2017.<br />

<br />
The term [[Sune]] (pronounced "soon", or less commonly "soo-nay") was coined by [[Lars Petrus]] for [[Petrus Method|his method]], and is the most widely recognized name for the sequence of moves and the case. The mirror/inverse alg/case is named ''[[Antisune]]'' (or ''Anti Sune''). Using double layers for the first and last moves it is called a ''[[Fat Sune]]''.<br />

<br />
Today's featured article is '''[[Skewb]]'''.<br />
<br />
<br />
The [[Skewb]] (originally named the ''Pyraminx Cube'') is a twistable [[puzzle]] in the shape of a cube that is cut diagonally 2 times along each of 4 axes. It is a cube-shaped puzzle. It consists of 6 [[center]] pieces and 8 [[corner]] pieces (four of which are attached to the central core). Unlike the [[Rubik's cube]], which turns around faces, the Skewb turns around axes that go through its corners. It is a [[deep-cut]] puzzle (i.e. each cut goes through the absolute center of the puzzle, and exactly half of the puzzle changes with each turn).<br />
<br />
This puzzle was originally called the Pyraminx Cube by [[Uwe Meffert]], but [[Douglas Hofstadter]] suggested the name "Skewb", and it has been called that ever since.<br />

The [[Ortega Method]], also known as the [[Varasano Method]], is a [[2x2x2]] and [[3x3x3]] [[speedsolving]] method named after [[Victor Ortega]] or [[Jeffrey Varasano]], depending on which method name is used. It was independently invented by [[Victor Ortega]] and [[Josef Jelínek]], whose ideas were inspired off of [[Jeffrey Varasano]]'s [[corners first]] method, which has sparked some naming controversy in the community started by [[Chris Olson]] after posting a video on YouTube about the matter. <br />
<br />
It is currently the most popular intermediate 2x2x2 solving method.<br />

The [[2x2x2 Cube]] (also known as a Pocket Cube or Mini Cube and normally referred to as the 2x2x2 or 2x2) is a [[twisty puzzle]] in the shape of a [[cube]] that is cut once along each of three axes.<br />
<br />
This puzzle only has 8 colored/solvable pieces: 8 [[corner]] pieces. The 2x2x2 cube has 3,674,160 possible positions (assuming one piece is always solved from orienting the puzzle), each of which can be solved in 11 turns ([[HTM]]) / 14 turns ([[QTM]]) or fewer.<br />

Today's featured article is '''[[Alinea Project]]'''.<br />
<br />
[[Alinea Project]] was an independent project started by [[Chris Tran]] developed with the goal of drastically improving [[3x3x3]] cubing hardware. The project was publicly revealed at [[CubingUSA Nationals 2017]] about five minutes into Tran's seminar titled "One Small Step for Magnets-- One Giant Leap for Cubing".<br />
<br />
The project included putting [[tensions]] in the [[core]] of the cube, greatly enlarging the [[Feet (hardware)|feet]] and [[torpedo]]s, using an easy-to-manufacture and stable method of embedding [[magnets]] into the pieces, and using self-lubricating internal plastic.<br />
<br />
The project has been halted due to high costs, adding up to US$3,396.34 for the cost of prototypes and testing.<br />

<br />
'''Sune''' is the most widely recognized name for the [[OLL]] case in which the edges are oriented and three corners are twisted counterclockwise, and also for the algorithm which solves it.<br />
<br />
== Name ==<br />
The term was coined by [[Lars Petrus]] for [[Petrus|his method]]. Sune is a male name in Sweden and is an iron age form for 'the son'; in modern Swedish that is 'sonen'. It is pronounced "soon-eh" ([suːnɛ]), but in cubing it has become far more common to be pronounced "soon" ([suːn]).<br />
<br />
== Algorithm ==<br />
The Sune is a [[2-gen]] [[algorithm]] that affects the [[LL|last layer]] of a [[3x3x3|Rubik's Cube]], and can be applied to other [[puzzle]]s. It is most canonically written as {{Alg|R U R' U R U2 R'}}<br />
<br />
The Sune can be written as a pure [[commutator]], but is most commonly recognized as a [[conjugate]]d commutator or a sequence of two commutators.<br />
<br />
== Variants ==<br />
* '''Anti-Sune''' {{Alg|R U2 R' U' R U' R'}}<br />
* '''Fat Sune''' {{Alg|r U R' U R U2 r'}}<br />
* '''Fat Anti-Sune''' {{Alg|r U2 R' U' R U' r'}}<br />
* '''Double Sune''' {{Alg|R U R' U R U' R' U R U2 R'}}<br />
* '''Super Sune''' {{Alg|R2 U R2' U R2 U2 R2'}}<br />
<br />
== An alternative name: the Anti-Chair ==<br />
In french speaking countries, Anti-Sune is also known as the '''chair''' (''L'histoire de la chaise'' in french). This naming has been popularized by the [[Francocube]] community, through a [[mnemonic device]] for [[beginner]]s presented in [https://www.francocube.com/cyril/rubiks-cube#croix this beginner tutorial]. This mnemonic device consists into repeating this little story: "He stands up ''(R)'', goes far away ''(U2)'', his chair falls ''(R')'', he comes back next to his chair ''(U')'', he straightens his chair ''(R)'', he goes back on his chair ''(U')'' and he sits down ''(R')''." Logically, as Anti-Sune is also called Chair, Anti-Chair is an alternative name of Sune.<br />

The [[3x3x3 cube]] (also known as "[[Rubik's]] cube" and "magic cube") was invented by [[Ernő Rubik]] in 1974, and was quickly unveiled in the early 1980s.<br />
<br />
This is a mechanical and geometric puzzle composed of with 26 elements (called [[cubie]]s), which can be moved with a system of axes, that is hidden in the center of the cube. Each of the six [[face]]s is covered by 9 [[sticker]]s, among six solid colours (traditionally being white, yellow, orange, red, blue, and green). The system of axes enables each layer to turn independently, thus mixing up the colours. For the puzzle to be [[solve]]d, each face must be a solid colour.<br />
<br />
It is said to be the world's best-selling toy, with over 350 millions cubes sold worldwide as of 2009.<br />
<br />
It has inspired many widely available variations such the [[2×2×2]], the [[3×3×3]], the [[4×4×4]], the [[5×5×5]], [[big cube|larger sizes ones]], the [[Pyraminx]] (tetrahedron), the [[Skewb Diamond]] (octahedron), the [[Megaminx]] (dodecahedron) or the [[Dogic]] (icosahedron). All of these items belong to a broad category of puzzles commonly referred to as "[[twisty puzzle]]s". Some [[twisty puzzle]]s are [[shape-shifting]] (such as the [[Square One]]) or [[custom-built]] (such as [[shape modification]]s of existing mechanisms).<br />
<br />
Many subjects have been built around [[cubing]]:<br />

<br />
This is a mechanical and geometric puzzle composed of with 26 elements (called [[cubie]]s), which can be moved with a system of axes, that is hidden in the center of the cube. Each of the six [[face]]s is covered by 9 [[sticker]]s, among six solid colours (traditionally being white, yellow, orange, red, blue, and green). The system of axes enables each layer to turn independently, thus mixing up the colours. For the puzzle to be [[solve]]d, each face must be a solid colour.<br />

It is said to be the world's best-selling toy, with over 350 millions cubes sold worldwide as of 2009.<br />
<br />
It has inspired many widely available variations such the [[2×2×2]], the [[3×3×3]], the [[4×4×4]], the [[5×5×5]], [[big cube|larger sizes ones]], the [[Pyraminx]] (tetrahedron), the [[Skewb Diamond]] (octahedron), the [[Megaminx]] (dodecahedron) or the [[Dogic]] (icosahedron). All of these items belong to a broad category of puzzles commonly referred to as "[[twisty puzzle]]s". Some [[twisty puzzle]]s are [[shape-shifting]] (such as the [[Square One]]) or [[custom-built]] (such as [[shape modification]]s of existing mechanisms).<br />
<br />
Many subjects have been built around [[cubing]]:<br />
