<div>'''Permutation of both layers''', abbreviated as '''PBL''', is a [[step]] used in a number of [[2x2x2]] methods (and thus [[corners first]] methods). Specifically, the [[Ortega method]] and the [[Guimond method]], perhaps the two most popular advanced [[2x2x2]] methods, both finish with a PBL step. When solving only corners, PBL has five unsolved cases, which can be recognized by the number of pairs on each side that are correctly permuted (a solved side has 4 pairs, an adjacent swap has 1 pair, and an opposite swap has 0 pairs), so the unsolved cases are 0+0, 1+0, 1+1, 4+0, and 4+1. [[Algorithm]]s for PBL (for 2x2x2 or CF) can be found at the [[Template:CxLLnav|CxLL]] pages (the grey cases in the topmost line).<br />
<br />
It is actually possible, in theory, to do PBL in one step for [[3x3x3]] or [[Square-1]] - in this case we would be permuting not only corners but the whole layers. No [[speedcubing]] method actually uses this, though, because there are about 800 cases in total and recognition is very difficult. For the [[Square-1]], many methods do PBL in two steps, by first solving the [[corner]]s of both layers and then doing the [[edges]] of both layers. Even though two layers are being permuted at once, though, solvers conventionally refer to the steps as simply [[CP]] and [[EP]].<br />

The first two algorithms (Y perm and A perm) only affect the top layer, and because of that, they can be used in LBL methods.<br />
<br />
Note that D moves are the same as U + y, just a different notation, what you do for real is something in between. The effect of it is that you transform F moves to R or L (D R makes the same turns as U F + y').<br />

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.<br />
<br />
The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.<br />
<br />
[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.<br />

<br />
== Approaches ==<br />
<br />
=== Petrus F2L ===<br />
<br />
Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.<br />
<br />
=== Fridrich F2L ===<br />
<br />
There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.<br />
<br />
The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.<br />

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.<br />
<br />
The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.<br />
<br />
[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.<br />
<br />

<br />
== Approaches ==<br />
<br />
=== Petrus F2L ===<br />
<br />
Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.<br />
<br />
=== Fridrich F2L ===<br />
<br />
There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.<br />
<br />
The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.<br />

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.<br />
<br />
The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.<br />
<br />
[[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.<br />
<br />

<br />
== Approaches ==<br />
<br />
=== Petrus F2L ===<br />
<br />
Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.<br />
<br />
=== Fridrich F2L ===<br />
<br />
There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.<br />
<br />
The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.<br />

'''PLL''' is the acronym for '''Permutation of the Last Layer'''. In this step, the pieces on the top layer have already been oriented ([[OLL (2x2x2)]]) so that the top face has all the same color, and they can now be moved into their solved positions.<br />
<br />
These algorithms [[Permutation|permute]] the top layer on a [[2x2x2]].<br />

<div>Although the [[2x2x2 cube]] can be considered as just the [[corner]]s of the [[3x3x3 cube]], there are several ways of [[Methods|solving]] it, ranging from simple to advanced. The best site for many of these methods, containing [[algorithm]]s and fuller explanations, is [http://erikku.er.funpic.org/rubik/Tutorials.html Erik's 2x2x2 tutorial page], which actually contains most of these methods. For any method it helps to be [[color-neutral]] so you can avoid bad cases.<br />
<br />
The best 2x2x2 solvers can solve the cube in a global average of under 2 seconds.<br />
<br />
== Basic Methods ==<br />
* [[3x3x3 Like Method]] - One of the easiest ways to solve the 2x2x2 is just like the 3x3x3. First, you insert the first layer corners, as in a 3x3x3 beginner's method, then orient the last layer, using an algorithm from 2-look OLL, pretending there is a cross on top, and finally do a PLL, switching two corners along with the two edges, or a three cycle of corners, if applies. Note that the 2x2x2 has a much higher chance of an OLL or PLL skip, as it has no edges. You can also sometimes use more efficient sequences, such as FRUR'U'F' for the "superman" orientation case.<br />
<br />
* [[LBL]] - This is an extension of the 3x3x3 method above. The first step is to solve one layer of the cube; this is an intuitive step, so you should try to figure out how to do it all during inspection, and do it in as few moves as you can. Then you can solve the orientation and permutation in two steps. Some cubers choose to learn to do these last two steps in one, by learning [[CLL]], which has 42 algorithms.<br />
<br />
== Intermediate Methods ==<br />
* [[Ortega]]<br />
* [[Guimond]]<br />
<br />
== Advanced Methods ==<br />
There are a couple of very advanced methods for solving the 2x2x2. Due to the magnitude of algorithms required for these methods, these methods are only used by several speed cubers.<br />
<br />
* [[CLL Method]] (42 algs)<br />
* [[SOAP Method]] (58 algs)<br />
* [[SS Method]] (60 algs)<br />
* [[OFOTA Method]] (92 algs)<br />
* [[EG Method]] (120 algs)<br />

'''Corners First''' methods, abbreviated as '''CF''', are [[speedcubing]] methods that solve all of the corners (relative to each other) before anything else. There are not very many serious CF solvers for [[3x3x3]] these days, because it can be hard to get under 20 seconds with a pure CF method, but CF methods are relatively easy to invent and were very popular in the [[1980s]]. At least in theory, CF methods exist for all puzzles with corners, although for many puzzles (such as [[big cube]]s) they are impractical for speedsolving. For the [[2x2x2]], on the other hand, there are only corners, so any method is in effect a CF method, and ideas from 2x2 solving can be applied to CF methods on any larger [[cube]] puzzle. The most popular methods for solving the corners are [[Guimond]], [[Ortega]], and [[CLL]]; there are many ways to do the edges, perhaps the most efficient of which is the [[Waterman]] method.<br />
<br />
==History==<br />
The first ever solve of a Rubik's Cube was by [[Ernő Rubik]] himself in 1974, and he used a corners first solution he developed himself over several weeks. One of the first published guides specifically intended for speedcubing was [[Jeffrey Varasano]]'s 1981 book ''Conquer the Cube in 45 Seconds'' which used a corners first solution. The first official speedcubing World record (in 1982) was done using corners first (22.95 secs by [[Minh Thai]]). Around that time [[Marc Waterman]] and [[Daan Krammer]] developed the [[Waterman Method]], a highly evolved corners-first method with more than 100 algorithms, allowing Marc Waterman to achieve sub-17-second averages and some of the fastest times of the 1980s.<br />
<br />
In the 21st century very little attention has been paid to corners-first methods for 3x3x3 cubes although there are similarities with the highly-efficient [[Roux Method]]. In 2017 a Roux-Waterman hybrid known as [[WaterRoux]] has been proposed.[https://www.speedsolving.com/forum/threads/the-waterroux-3x3-method-thread.64140/]<br />
<br />
== Beginner CF Methods ==<br />
There are no specifically named methods in this group, but a typical beginner CF method may look like this:<br />
<br />
'''Corners:'''<br />
* Solve the corners of the first layer using intuition.<br />
* Orient the [[LL]] corners using R U R' U' R' F R F' or a similar algorithm.<br />
* Permute the [[LL]] corners using a 3 cycle of corners (A Permutation)<br />
'''Centres:'''<br />
* Move centres into position using slice turns (trivial).<br />
'''Edges:'''<br />
* Place the edges of the E layer using moves like ([[AUF]]) + M' R U' M U R'.<br />
* Place the edges of first layer using M' U M or M' U2 M.<br />
* Orient the last layer edges using [[EOLL#EOLL preserving corners|EOLL]].<br />
* Permute the last layer edges with [[EPLL]] (for the most basic methods this can be done with only the [[PLL#U Permutation : a|U-perm]]).<br />

<div>''A '''cuboid''' is a rectangular puzzle that is not a power of 3 (NxNxN), usally two of the axis are dived the same and the third one is diffrent but more uncommon types can have all three diffrent, like 2x3x4.<br />

<hr />
<div>The '''Void cube''' is a [[puzzle]] based on the [[3x3x3 cube]]. It features a different mechanism that makes the puzzle entirely hollow. Unlike the normal 3x3x3 cube, it does not feature [[center|centers]]. It can be solved like a normal cube, except that the absence of centers allows for two corners or two centers to be swapped with the rest of the cube solved, which is not possible on the normal cube. This situation can be resolved by doing a 90 degree E slice move, taking out the middle layer edges, putting them into their correct spots, and then solving the last layer.<br />

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.<br />
<br />
The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.<br />
<br />
[[2-gen]] F2L, most pairs (30:42) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.<br />
<br />
<br clear=all><br />
<br />
== Approaches ==<br />
<br />
=== Petrus F2L ===<br />
<br />
Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.<br />
<br />
=== Fridrich F2L ===<br />
There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up, and then inserted into the correct slot. A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers.<br />
<br />
The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.<br />

'''First Two Layers''', or '''F2L''' are normally the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes.<br />
<br />
The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step.<br />
<br />
[[2-gen]] F2L, most pairs (30:42) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and sovle the pair to the back slot using only RU. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.<br />

== Approaches ==<br />
<br />
=== Petrus F2L ===<br />
<br />
Another way to solve the 'F2L' is by building blocks, common during the first two layers of the [[Petrus]] method.<br />
<br />
=== Fridrich F2L ===<br />
There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up, and then inserted into the correct slot. A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers.<br />
<br />
The concept of pairing up four corner/edge pairs was first proposed by [[René Schoof]] in 1981.<br />

<hr />
<div>The '''4-Look Last Layer''' involves completing the last layer in four steps or ''looks''. It is an intermediate step between the [[beginner LBL]] method and learning [[Fridrich|full Fridrich]]. It is generally broken down into [[2-look OLL]] (orientation of edges, followed by orientation of corners) and [[2-look PLL]] (permutation of corners, followed by permutation of edges). Achieving 4LLL requires knowledge of 16 algorithms or 14 excluding mirrors. While progressing from '''4LLL''' to [[2LLL]] a speedcuber will typically learn all 21 [[PLL]]s first, to achieve a [[3-look last layer]]. Eventually, learning the final 57 [[OLL]] cases will achieve the 2-look last layer used in full [[Fridrich]].<br />
<br />
Another possible breakdown is to use 2-look [[CLL]] ([[CO]]-[[CP]]) and 2-look [[ELL]] ([[EO]]-[[EP]]). This can later become three different 3-looks, full CLL and 2-look ELL, 2-look CLL and full ELL but also CO, [[CPEOLL]] and [[EPLL]]. This suggestion only uses 26 algorithms in total, the drawback is that the mid step is not of much use when expanding to 2-look.<br />
<br />
Both the 2-Look CLL and ELLs can also be done with permutations before orientations. This takes learning 14 algorithms (or 16 if including mirrored algorithms). Splitting CLL into 4-look reduces the algorithms needed for permutation from 2 to 1, and the number needed for corner orientation to 1 (or 2 including its mirror). Splitting ELL into 4-look reduces the number of required algorithms for permutation from 4 to 1 (or 2 including its mirror) and reduces the permutation to 1 algorithm.<br />
<br />
Another breakdown is [[BLL]], which uses a 2-Look [[LLEF]] and 2-Look [[CLL]] ([[Corner_Orientation#OCLL-EPP|OCLL-EPP]] - [[CPLL]]) that respects the edges. This can develop into a [[3LLL]] by perform the [[LLEF]] in one step. This 3LLL method uses only 24 algorithms (26 including reuses), and can be later expanded to a [[2LLL]] that uses 98 algorithms (exactly 100 including reuses).<br />
