'''CLL, Corners of Last Layer''', a method that solves the [[last layer]] [[corner]]s in one [[algorithm]].

CLL is not to be confused with [[COLL]] that is an abbrevation for exactly the same name but COLL does also preserve LL edge orientation, sometimes you will need longer algorithms for that.

There are two different sets of CLL, one that is used for [[corners first]] (the [[Waterman method]]) and the [[2x2x2 cube]] and one that preserves the [[first two layers]] on the [[3x3x3 cube]]. In the latter case the LL edges are solved after the CLL using [[ELL]].

== As a 2x2x2 Speedsolving Method ==

The first stage of CLL for the 2x2x2 consists of completely solving one layer of the cube (both orientation and permutation) as in the [[Layer by layer|Layer-By-Layer method]]. Then, using one of 42 algorithms (2 of which are PLLs), you solve the remaining orientation and permutation of the last layer (thus giving a 1 Look Last Layer). The algorithms needed are given in the [[CxLL|CxLL pages]]. This method is also named the Waterman method after the 1980's master cuber [[Marc Waterman]] from the Netherlands who was using it for his [[corners first]] method back then ([http://rubikscube.info/waterman/index.php the Waterman documentation]).

==History==
CLL was first officially used by [[Guus Razoux Schultz ]] ([http://www.worldcubeassociation.org/results/p.php?i=1982RAZO01 WCA]) during the [[WC 1982]].

'''Erik Johnson F2L''' (abbreviation '''EJF2L''', also known as '''EJLS''' ('''EJ Last Slot''')), is an [[F2L]] technique proposed by [[Erik Johnson]]. It uses a subset of the [[MGLS]] [[CLS]] step, using only cases where the F2L corner is inserted, but not necessarily oriented. It is used in methods which pre-orient the LL edges such as [[ZZ]] or [[Petrus]].

The idea behind the method is that while solving the F2L, one of corners can be inserted in the wrong orientation, and is later fixed while orienting the last layer corners using CLS.

Superflip

2011-08-05T12:03:50Z

JustinJ: Pointed out it's been proven that 20 moves is the maximum.

[[Image:Superflip.png|frame|The superflip.]]

The '''superflip''' is a famous position of the [[3x3x3]] where all corners are solved, and all edges are in the correct location but flipped. Despite its symmetry, this is an extremely difficult pattern, which is known to require 20 moves [[HTM]] to solve (in fact it was the first position that was proven to require that many moves). No position exists that requires more than 20 moves.

The superflip also has a few interesting properties because of the way it interacts with the [[Rubik's cube group]]. If you do a [[commutator]] with the superflip and any other algorithm, you will always end up back at the solved state; the superflip is also self-inverse, which means doing it twice will bring you back to the solved state. Also, because the superflip is completely symmetrical but not solved, any move will bring it to a position that is easier to solve.

One optimal solution in HTM for the superflip is U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2. The superflip also requires a minimum of 24 quarter turns to solve, and a minimum of 16 slice turns. One example of an optimal solution which requires 16 slice turns is S U B2 D2 M D' M2 S U R2 D M2 U B2 U S2. Another solution which requires 24 turns [[STM]] is MU'MU'MU'MU'yz'MU'MU'MU'MU'yz'MU'MU'MU'MU'. This is particularly easy to remember, as it is simply (MU')x4 followed by a yz'. This is repeated three times.

JustinJ: /* Where can I find a scramble generator? */ wording

== Frequently Asked Questions ==
Feel free to fill in the answers. Link to posts or sites you feel are relevant or provide your own original content.

Do *not* copy other people's content from their sites and simply paste it in here. That's called plagiarism and it's stealing.
=== Cubes ===
==== What is the best cube? ====
It really depends on your personal preference. For DIYs, the most common cubes among the worlds best are the Alpha-V, ShengEn F-II, and the very popular DaYan GuHong or LingYun cubes.

For more information, see the [[Cube Hardware]] page.

==== Where can I buy cubes? ====
You can try [http://www.rubikfans.com: Rubikfans], [http://www.rubiks.com: Rubik's official Store], [http://www.9spuzzles.com: 9spuzzles], [http://www.puzl.co.uk: puzl.co.uk ], [http://www.cube4you.com: Cube4You], [http://cubefans.com/: Cubefan's], or other places such as ebay. Cubefans and Cube4You are the same store, it's just that Cube4You works best on Internet Explorer. For specialty products, try [http://www.mefferts.com/: Meffert's] and the [https://v-cubes.com/ecom/home.php?cat=248: V Cube shop]. Also, it's a good idea to check some garage sales or flea markets, as puzzles have been found for much cheaper than actual value.

Be aware that buying "knock-offs" (illegal copies of currently patented puzzles) is frowned upon by many forum members. A "[[Knock-Off Policy|knock-off policy]]" is currently under discussion.

@ See [http://www.speedsolving.com/forum/showthread.php?t=15237 speedsolving.com discussion]

==== How do I lubricate my cube? ====
You can either take a piece or two out and spray the lubricant in directly, or disassemble and fully spray the lubricant on every piece with sweeps. There are many tutorials in youtube if you need help. Also, check youtube for techniques to lubricate big cubes.

The best lubricants tend to be silicone based. Products like Jig-a-Loo and CRC Heavy Duty Silicone spray are very popular among cubers. There is a lubricant made specially for cubing which can be bought at [http://stores.shop.ebay.com/PuzzleProz Puzzleproz]. You should never use WD-40 lube on your cube as it contains petroleum distillates which can damage the plastic. Some people do use petroleum jelly to break in really stiff cubes such as storeboughts, but it should never be used as lube.

For more info on lubricants see the [[lubrication]] page.

==== How do I keep my screws from unscrewing when I turn the Cube? ====
Several options:
# Replace the core
# Replace the screws
# Glue or locktite them in place
==== Textured or Smooth Tiles? ====
Both of them are durable, so if you are looking for a more permanent replacement for your stickers, this is the way to go.

As for which type, it's all in your preference. Textured will have more of a grip which can help if you have sweaty, oily, moist, etc. hands since it will keep it from slipping too much.

Smooth, however, does still have texture. It just so happens to have a little bit less, so if you don't want something quite as bumpy, get the smooth tiles.

=== Notation ===
==== What does <insert some notation here> mean? ====
The official notation of the World Cube Association can be found here: [http://www.worldcubeassociation.org/regulations/#notation]

Wikipedia also has a description of the notation in a different format: [http://en.wikipedia.org/wiki/Rubik%27s_Cube#Move_notation]

There are many other references on the Net, try googling "rubik cube notation" if you don't like either of the above.
Here's a page with pictures: http://www.cubewhiz.com/notation.html

==== The notation I'm asking about isn't in the WCA regulations, how do I decipher how to turn it? ====
Some older notation used "w" for a wide turn, so Rw would be the same as r in WCA notation.
(This topic can be added to)

==== The notation I'm asking about came from a Japanese cuber site, how do I decipher these also? ====
Japanese cubers commonly use a different notation for cube rotations. (r) means to rotate the entire cube in the direction you would make an R turn. Similarly, (u') would be the same as a y' rotation.

=== Timers ===
==== Where can I buy a timer like they use in competition? ====
* [http://www.speedstacks.com: speedstacks.com] is probably the most reliable source for timers, but they only ship to the US and Canada.

* [http://www.ebay.com: eBay] sometimes you can find a cheap deal.
It's also possible to make your own timer [http://grrroux.free.fr/workshop/workshop.html].

@ see related threads on forum [http://www.speedsolving.com/forum/showthread.php?t=9624 here] and [http://www.speedsolving.com/forum/showthread.php?t=6333 here].

==== Are there timers on the Internet? ====
Yes.

Try [http://www.qqtimer.net qqTimer], [http://www.cubetimer.com Cubetimer], [http://www.rubetimer.com Rubetimer], or look for other timers. Also, [http://www.cubemania.com Cubemania] is a site that times and keeps track of all the solves you submit. The [[Web-based Software]] Wiki page also has up-to-date info on online timers.

==== Can I download a timer for my computer/phone/psp? ====
You can download CCT [http://cube.garron.us/cct/] for your computer. This is the timer that is very popular with many features like being able to connect a speedstacks timer with a data port to the computer and use it with CCT. Another great timer is [http://www.strangepuzzle.com/jnetcube.html JNet Cube].

Prisma Puzzle Timer (PPT) is a very good timer that is becoming more and more popular. This timer gives graphs, and other data charts for sessions. You can find all of it's features in the forum discussion [http://www.speedsolving.com/forum/showthread.php?25790-Prisma-Puzzle-Timer here] and on the website [https://bitbucket.org/walter/puzzle-timer/ here]

On iPhone and iPod touch, [http://itunes.apple.com/us/app/iitimer/id375822731?mt=8 iiTimer] is a port of qqTimer that works very well.

On Android, [https://market.android.com/details?id=com.jgouly.jjtimer jjTimer] and [https://market.android.com/details?id=com.jjtimer JustInTime] are both good options.

Note that for solves that take more than 15 seconds, a simple analog clock will work just fine if you don't need precise timing.

==== Where can I find a scramble generator? ====
Most speedcubing timers include scrambler generators.
If your timer does not have scrambles, you can use [http://www.worldcubeassociation.org/regulations/#scrambling this page] to find a scramble generator for your puzzle. The [[Web-based Software]] Wiki page also has up-to-date info on online scramblers.

==== What is standard deviation? ====
http://en.wikipedia.org/wiki/Standard_deviation
In probability theory and statistics, standard deviation is a measure of the variability or dispersion of a population, a data set, or a probability distribution. A low standard deviation indicates that the data points tend to be very close to the same value (the mean), while high standard deviation indicates that the data are spread out over a large range of values.

=== Competitions ===
==== Where are the rules for WCA competitions? ====
On the [http://www.worldcubeassociation.org/regulations/ WCA site] of course!

==== How fast do I need to be to compete? ====
There's no requirement for speed to participate in most competitions. Even high level competitions like the US Nationals are open to all, if you see a time listed for "prequalification", this is a time that allows you to skip the qualifying round. If you are slower than that time you will still be allowed to take part in the qualifications.

If you have the opportunity to attend a competition, even if you're not very fast, most experienced competitors would advise you to go for the social interaction and experience.

=== Methods ===
==== What is the fastest method? ====
There is no ''ultimate method'', its really down to personal preference. The most popular [[3x3x3 Speedcubing Methods | speedcubing method]] is currently Fridrich, although other methods such as [[Petrus]], [[Roux]] and [[ZZ]] are rising in popularity. [[Fridrich]] is currently used by many of the top speedcubers, and is as such believed to be the fastest method. However, others attribute this to its popularity. The most obvious/natural progression from the [[beginner LBL]] method is Fridrich, which may explain its popularity. Being the most popular means it gains the most support and development, and is also more likely to be adopted by a talented cuber. More info can be found in the [http://www.speedsolving.com/forum speedsolving forums], where this often comes up as topic of debate.

==== What is the easiest method? ====
The easiest [[Complete Method List | method]] to learn is probably the beginner's [[layer-by-layer]] (LBL) method in which you solve the first, second, and the finally the last layer one by one. It's pretty basic, therefore easy to learn. However, this method however is relatively inefficient and is hard to achieve good times with. Other [[3x3x3 Beginner Methods | beginner]] methods exist, focusing on lower numbers of algorithms and/or more intuitive solving. Compared to the others, the [[LBL]] method has the easiest transition to the popular [[Fridrich]] speedcubing method.

==== What is the method that uses the fewest moves? ====
The most popular method for Fewest Moves solving is the [[Petrus]] method. Although it is designed for speed, it tends to have a very good move efficiency compared to other methods. The [[Heise]] method is another method that was designed specifically for move efficiency rather than speed. It is highly intuitive and very difficult to master. Other methods can be still be made efficient if you plan your moves carefully.
More info on FM can be found on the [[Fewest Moves]] page.

==== Should I learn algorithms for F2L or learn it intuitively? ====
That is entirely your choice. Learning the algs isn't entirely hard since most cases can be seen and understood by practicing the algorithms. Intuitively, it will take practice to be able to do with speed and efficiency.

Most people choose to learn intuitively and with some practice, it can be just as fast. Intuitive F2L is may take more time to master but it is generally preferred because it allows for the use of advanced speed-reducing techniques such as multislotting and the use of empty slots.

==== How can I get faster? ====
Practice, practice, practice. That is the key way to get speed. Normally, with some work, your times will gradually drop without you doing anything.

If you haven't, try learning an advanced method. That should help you lower your times considerably.

Work on lowering your move count, look ahead and experiment with tricks.

Learn new algorithms.

Unglue your eyes from your computer screen, pick up your puzzle, and try to get faster. :p

==== I think I invented a new method, did I? ====
Probably not. If you haven't studied and don't fully understand the concepts behind all the major solving methods (CFOP, Petrus, Roux, ZZ, Waterman) and know the basic philosophy of the advanced variations (MGLS, ZB, Heise) then don't even bother asking.

=== Miscellaneous ===
==== Should I make a new web site about cubing? ====
Probably not unless you're actually going to provide something fresh and new and not just rehash the information already available on the 'net.
@see the Wiki [[Cubing Sites | list of cubing sites]]

==== What does AUF mean? ====
Adjust U Face
==== What does XXX mean? ====
Macky created a great glossary of cubing terms. This is a great first stop if you see a term or abbrevation you don't understand.

==== Are there timers on the Internet? ====
Yes.

Try [http://www.qqtimer.net qqTimer], [http://www.cubetimer.com Cubetimer], [http://www.rubetimer.com Rubetimer], or look for other timers. Also, [http://www.cubemania.com Cubemania] is a site that times and keeps track of all the solves you submit. The [[Web-based Software]] Wiki page also has up-to-date info on online timers.

==== Can I download a timer for my computer/phone/psp? ====
You can download CCT [http://cube.garron.us/cct/] for your computer. This is the timer that is very popular with many features like being able to connect a speedstacks timer with a data port to the computer and use it with CCT. Another great timer is [http://www.strangepuzzle.com/jnetcube.html JNet Cube].

Prisma Puzzle Timer (PPT) is a very good timer that is becoming more and more popular. This timer gives graphs, and other data charts for sessions. You can find all of it's features in the forum discussion [http://www.speedsolving.com/forum/showthread.php?25790-Prisma-Puzzle-Timer here] and on the website [https://bitbucket.org/walter/puzzle-timer/ here]

On Android, [https://market.android.com/details?id=com.jgouly.jjtimer jjTimer] and [https://market.android.com/details?id=com.jjtimer JustInTime] are both good options.

Note that for solves that take more than 15 seconds, a simple analog clock will work just fine if you don't need precise timing.

==== Where can I find a scramble generator? ====
Most timers (customized for cubing) come preset with scrambles.
If your timer does not have scrambles, you can use [http://www.worldcubeassociation.org/regulations/#scrambling this page] to find a scramble generator for your puzzle. The [[Web-based Software]] Wiki page also has up-to-date info on online scramblers.

==== What is standard deviation? ====
http://en.wikipedia.org/wiki/Standard_deviation
In probability theory and statistics, standard deviation is a measure of the variability or dispersion of a population, a data set, or a probability distribution. A low standard deviation indicates that the data points tend to be very close to the same value (the mean), while high standard deviation indicates that the data are spread out over a large range of values.

=== Competitions ===
==== Where are the rules for WCA competitions? ====
On the [http://www.worldcubeassociation.org/regulations/ WCA site] of course!

==== How fast do I need to be to compete? ====
There's no requirement for speed to participate in most competitions. Even high level competitions like the US Nationals are open to all, if you see a time listed for "prequalification", this is a time that allows you to skip the qualifying round. If you are slower than that time you will still be allowed to take part in the qualifications.

If you have the opportunity to attend a competition, even if you're not very fast, most experienced competitors would advise you to go for the social interaction and experience.

=== Methods ===
==== What is the fastest method? ====
There is no ''ultimate method'', its really down to personal preference. The most popular [[3x3x3 Speedcubing Methods | speedcubing method]] is currently Fridrich, although other methods such as [[Petrus]], [[Roux]] and [[ZZ]] are rising in popularity. [[Fridrich]] is currently used by many of the top speedcubers, and is as such believed to be the fastest method. However, others attribute this to its popularity. The most obvious/natural progression from the [[beginner LBL]] method is Fridrich, which may explain its popularity. Being the most popular means it gains the most support and development, and is also more likely to be adopted by a talented cuber. More info can be found in the [http://www.speedsolving.com/forum speedsolving forums], where this often comes up as topic of debate.

==== What is the easiest method? ====
The easiest [[Complete Method List | method]] to learn is probably the beginner's [[layer-by-layer]] (LBL) method in which you solve the first, second, and the finally the last layer one by one. It's pretty basic, therefore easy to learn. However, this method however is relatively inefficient and is hard to achieve good times with. Other [[3x3x3 Beginner Methods | beginner]] methods exist, focusing on lower numbers of algorithms and/or more intuitive solving. Compared to the others, the [[LBL]] method has the easiest transition to the popular [[Fridrich]] speedcubing method.

==== What is the method that uses the fewest moves? ====
The most popular method for Fewest Moves solving is the [[Petrus]] method. Although it is designed for speed, it tends to have a very good move efficiency compared to other methods. The [[Heise]] method is another method that was designed specifically for move efficiency rather than speed. It is highly intuitive and very difficult to master. Other methods can be still be made efficient if you plan your moves carefully.
More info on FM can be found on the [[Fewest Moves]] page.

==== Should I learn algorithms for F2L or learn it intuitively? ====
That is entirely your choice. Learning the algs isn't entirely hard since most cases can be seen and understood by practicing the algorithms. Intuitively, it will take practice to be able to do with speed and efficiency.

Most people choose to learn intuitively and with some practice, it can be just as fast. Intuitive F2L is may take more time to master but it is generally preferred because it allows for the use of advanced speed-reducing techniques such as multislotting and the use of empty slots.

==== How can I get faster? ====
Practice, practice, practice. That is the key way to get speed. Normally, with some work, your times will gradually drop without you doing anything.

If you haven't, try learning an advanced method. That should help you lower your times considerably.

Work on lowering your move count, look ahead and experiment with tricks.

Learn new algorithms.

Unglue your eyes from your computer screen, pick up your puzzle, and try to get faster. :p

==== I think I invented a new method, did I? ====
Probably not. If you haven't studied and don't fully understand the concepts behind all the major solving methods (CFOP, Petrus, Roux, ZZ, Waterman) and know the basic philosophy of the advanced variations (MGLS, ZB, Heise) then don't even bother asking.

=== Miscellaneous ===
==== Should I make a new web site about cubing? ====
Probably not unless you're actually going to provide something fresh and new and not just rehash the information already available on the 'net.
@see the Wiki [[Cubing Sites | list of cubing sites]]

==== What does AUF mean? ====
Adjust U Face
==== What does XXX mean? ====

== Frequently Asked Questions ==
Feel free to fill in the answers. Link to posts or sites you feel are relevant or provide your own original content.

Do *not* copy other people's content from their sites and simply paste it in here. That's called plagiarism and it's stealing.
=== Cubes ===
==== What is the best cube? ====
It really depends on your personal preference. For DIYs, the most common cubes among the worlds best are the Alpha-V, ShengEn F-II, and the very popular DaYan GuHong or LingYun cubes.

For more information, see the [[Cube Hardware]] page.

==== Where can I buy cubes? ====
You can try [http://www.rubikfans.com: Rubikfans], [http://www.rubiks.com: Rubik's official Store], [http://www.9spuzzles.com: 9spuzzles], [http://www.puzl.co.uk: puzl.co.uk ], [http://www.cube4you.com: Cube4You], [http://cubefans.com/: Cubefan's], or other places such as ebay. Cubefans and Cube4You are the same store, it's just that Cube4You works best on Internet Explorer. For specialty products, try [http://www.mefferts.com/: Meffert's] and the [https://v-cubes.com/ecom/home.php?cat=248: V Cube shop]. Also, it's a good idea to check some garage sales or flea markets, as puzzles have been found for much cheaper than actual value.

Be aware that buying "knock-offs" (illegal copies of currently patented puzzles) is frowned upon by many forum members. A "[[Knock-Off Policy|knock-off policy]]" is currently under discussion.

@ See [http://www.speedsolving.com/forum/showthread.php?t=15237 speedsolving.com discussion]

==== How do I lubricate my cube? ====
You can either take a piece or two out and spray the lubricant in directly, or disassemble and fully spray the lubricant on every piece with sweeps. There are many tutorials in youtube if you need help. Also, check youtube for techniques to lubricate big cubes.

The best lubricants tend to be silicone based. Products like Jig-a-Loo and CRC Heavy Duty Silicone spray are very popular among cubers. There is a lubricant made specially for cubing which can be bought at [http://stores.shop.ebay.com/PuzzleProz Puzzleproz]. You should never use WD-40 lube on your cube as it contains petroleum distillates which can damage the plastic. Some people do use petroleum jelly to break in really stiff cubes such as storeboughts, but it should never be used as lube.

For more info on lubricants see the [[lubrication]] page.

==== How do I keep my screws from unscrewing when I turn the Cube? ====
Several options:
# Replace the core
# Replace the screws
# Glue or locktite them in place
==== Textured or Smooth Tiles? ====
Both of them are durable, so if you are looking for a more permanent replacement for your stickers, this is the way to go.

As for which type, it's all in your preference. Textured will have more of a grip which can help if you have sweaty, oily, moist, etc. hands since it will keep it from slipping too much.

Smooth, however, does still have texture. It just so happens to have a little bit less, so if you don't want something quite as bumpy, get the smooth tiles.

=== Notation ===
==== What does <insert some notation here> mean? ====
The official notation of the World Cube Association can be found here: [http://www.worldcubeassociation.org/regulations/#notation]

Wikipedia also has a description of the notation in a different format: [http://en.wikipedia.org/wiki/Rubik%27s_Cube#Move_notation]

There are many other references on the Net, try googling "rubik cube notation" if you don't like either of the above.
Here's a page with pictures: http://www.cubewhiz.com/notation.html

==== The notation I'm asking about isn't in the WCA regulations, how do I decipher how to turn it? ====
Some older notation used "w" for a wide turn, so Rw would be the same as r in WCA notation.
(This topic can be added to)

==== The notation I'm asking about came from a Japanese cuber site, how do I decipher these also? ====
Japanese cubers commonly use a different notation for cube rotations. (r) means to rotate the entire cube in the direction you would make an R turn. Similarly, (u') would be the same as a y' rotation.

=== Timers ===
==== Where can I buy a timer like they use in competition? ====

Probably not. If you haven't studied and don't fully understand the concepts behind all the major solving methods (CFOP, Petrus, Roux, ZZ, Waterman) and know the basic philosophy of the advanced variations (MGLS, ZB, Heise) then don't even bother asking.

=== Miscellaneous ===
==== Should I make a new web site about cubing? ====
Probably not unless you're actually going to provide something fresh and new and not just rehash the information already available on the 'net.
@see the Wiki [[Cubing Sites | list of cubing sites]]

==== What does AUF mean? ====
Adjust U Face
==== What does XXX mean? ====
Macky created a great glossary of cubing terms. This is a great first stop if you see a term or abbrevation you don't understand.

'''OPLL''', also known as '''lazy ZBLL''' is a subset of the [[ZBLL]] last layer method. If you have a Headlights of Bowtie [[OLL]] case, then most of the time, it can be solved by a conjugate of a [[PLL]], so no new algorithms need to be learned if you already know [[PLL]] (Conjugate is [A B A']).

Please note that because not everyone uses the same PLL's, the first listed case may not work for you. Because of this, the PLL is listed inside the brackets, feel free to subsitute it.

'''Lars Petrus''' is a Swedish speedcuber currently living in Mountain View, California (Bay Area). He is best known for inventing the [[Petrus Method]] for [[3x3]] speedsolving, and for his achievements in [[Fewest Moves]].

== Inventor of Petrus method ==
Lars invented his method in the early 1980s, at a time when almost everyone else was using a basic [[layer-by-layer]] or [[corners first]] method. His method is very intuitive and based on building around a corner, so as to have as many free sides as possible for most of the solve. Because this approach can be very efficient, it is very popular for [[Fewest Moves]] solving.

== Official Results ==
Lars won the 1981 Swedish championships using his method, and thus became the Swedish representation for the [[World Rubik's Cube Championship 1982]], where he placed 4th with a best time of 24.57. Lars's current best times in competition for the [[3x3]] event are a 16.64 second single and a 20.48 second average of 5.

Lars won 3x3 Fewest Moves at the [[World Championship 2005]] with a 38-move solution, making him the World Champion between 2005 and 2007. Lars also broke the 3x3 [[OH]] European record several times in 2004 and 2005.

== Trivia ==
* Lars has made [http://lar5.com/ikea/index.html The IKEA Dictionary], the only one of its kind.
* Lars named many well-known algorithms, including [[Sune]], [[Niklas]], [[Bruno]], and [[Benny]].
* A movie is being made based on a dream Lars had in 2010 and posted about as his Facebook status.
* The man is brilliant!

Last Layer

2011-02-05T23:33:38Z

JustinJ: small typo

[[Image:LL higlight.jpg|thumb|160px|The Last Layer]]
The '''Last Layer''' (normally abbrevated as '''LL''') is the layer that must be solved on a [[cube]] when all of the other layers have already been finished, normally assumed to refer to the U layer. Thus any last layer steps will be the last few steps of a method. The last layer is very often found with a prefix that refers to what part of the last layer is being solved in the particular [[method]], such [[OLL]] (orienting the pieces), [[PLL]] (permuting the pieces), or [[CxLL]] (solving the corners).

There is no practical method that solves a completely scrambled last layer in one step every time, because there are far too many cases to learn (although the [[ZBLL]] method, which solves the last layer when edges are already oriented, is close to this level of difficulty): not counting inverses or mirrored positions, there are a total of 1,211 cases. Because of this, the last layer is always solved in multiple steps. The number of steps is counted in numbers of [[looks]] (the number of separate algorithms needed to finish the cube). The vast majority of [[speedcuber]]s today use a two-look last layer (2LLL): possible ways to do this include [[OLL]]/[[PLL]] and [[CLL]]/[[ELL]].

'''Lukasz Cialon''' is a Polish speedcuber. He was one of the first cubers to specialize in 2x2, dominating competitions from 2005-2007. He popularized complete layer + [[CLL]] as a 2x2 method, which had previously been avoided because of the large number of algorithms and the relative unpopularity of 2x2.

OLLCP-A

2011-02-05T20:26:56Z

JustinJ: /* LF-flip */ Added an alg

'''CPEOLL''', ''corner permutation and edges orientation of the last layer'', an [[experimental method]] for the [[3x3x3 cube]] that [[permute]]s the [[last layer]] [[corner]]s and [[orient]]s the last layer [[edge]]s preserving [[F2L]]. This is the second last step and the goal is to reach [[EPLL]]. Normally it would be used as a add on to the [[Fridrich method]] the times [[CO]] skips (occures 1:27 times) but it may be used as a second step in a 3-look last layer where the first step is to orient the corners.

CPEOLL is a sub group of CEOLL or CLLEO (CLL + EO), the same as OCPLL or [[OLLCP]] (OLL + CP), a very advanced method with more than 300 cases that solves all last layer but EPLL in one look.

* [[Fridrich Method]]
* [http://www.speedsolving.com/forum/showthread.php?t=23005 Thread discussing this method]

=CPEOLL cases=
There are 15 cases, three of them have corners correctly permuted ([[CLL]] skip) and may be solved in one look using [[ELL]], two has got edges oriented and may be solved in one look using [[PLL]] ([[OLL]] skip). Removing those cases it is only 10 left (2 are mirror cases) and of those 4 may be solved using [[J-PLL]] + M setup and one can be solved using [[Y-PLL]] (or [[V-PLL]]) with a M move setup.

'''PLL''' is the Permutation of the [[Last Layer]], the last step of many speedsolving methods. In this step, the pieces on the top layer have already been oriented ([[OLL]]) so that the top face has all the same color, and they can now be moved into their solved positions. There are 21 PLLs (13 if you count mirrors and inverses as being the same) and each one is named after a letter. The following page gives a list of all of the PLLs, along with a picture and a list of common [[algorithm]]s for each one. The diagrams below are top views of where you want the pieces to go. For example, the [[PLL#T_Permutation|T Permutation]] (or 'T perm') swaps the UL and UR edges, as well as the UFR and UBR corners. Make sure to try out all of the available algorithms for a case to see which one feels the fastest to you - the same algorithm may not be the fastest for everyone, and shorter algorithms are not always faster than longer ones. PLL is a subgroup of [[ZBLL]].

==Permutations of Edges Only==
This subgroup, [[EPLL]] is used as a [[sub step]] for many speedsolving methods, for example in the [[VH method]] ([[COLL]]).

{{H-PLL}}
{{U-PLL(a)}}
{{U-PLL(b)}}
{{Z-PLL}}

==Permutations of Corners Only==
This is also known as [[CPLL]] (Corner Permute Last Layer). There is one more case in this group, the X-PLL but that is the same alg as [[H-PLL]] + U2, see [[EPLL]].

'''PLL''' is the Permutation of the [[Last Layer]], the last step of many speedsolving methods. In this step, the pieces on the top layer have already been oriented ([[OLL]]) so that the top face has all the same color, and they can now be moved into their solved positions. There are 21 PLLs (13 if you count mirrors and inverses as being the same) and each one is named after a letter. The following page gives a list of all of the PLLs, along with a picture and a list of common [[algorithm]]s for each one. The diagrams below are top views of where you want the pieces to go. For example, the [[PLL#T_Permutation|T Permutation]] (or 'T perm') swaps the UL and UR edges, as well as the UFR and UBR corners. Make sure to try out all of the available algorithms for a case to see which one feels the fastest to you - the same algorithm may not be the fastest for everyone, and shorter algorithms are not always faster than longer ones. PLL is a subgroup of [[ZBLL]].

==Permutations of Edges Only==
This subgroup, [[EPLL]] is used as a [[sub step]] for many speedsolving methods, for example in the [[VH method]] ([[COLL]]).

{{H-PLL}}
{{U-PLL(a)}}
{{U-PLL(b)}}
{{Z-PLL}}

==Permutations of Corners Only==
This is also known as [[CPLL]] (Corner Permute Last Layer). There is one more case in this group, the X-PLL but that is the same alg as [[H-PLL]] + U2, see [[EPLL]].

PBL

JustinJ: Added some algs

'''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).

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]].

The first two algorithms (Y perm and A perm) only effects the top layer, and because of that, they can be used in LBL methods.

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').

PLL

2010-08-21T01:17:15Z

JustinJ: /* J Permutation : b */

__NOTOC__
'''PLL''' is the Permutation of the [[Last Layer]], the last step of many speedsolving methods. In this step, the pieces on the top layer have already been oriented ([[OLL]]) so that the top face has all the same color, and they can now be moved into their solved positions. There are 21 PLLs (13 if you count mirrors and inverses as being the same) and each one is named after a letter. The following page gives a list of all of the PLLs, along with a picture and a list of common [[algorithm]]s for each one. The diagrams below are top views of where you want the pieces to go. For example, the [[PLL#T_Permutation|T Permutation]] (or 'T perm') swaps the UL and UR edges, as well as the UFR and UBR corners. Make sure to try out all of the available algorithms for a case to see which one feels the fastest to you - the same algorithm may not be the fastest for everyone, and shorter algorithms are not always faster than longer ones. PLL is a subgroup of [[ZBLL]].
{{PLL}}

Note that all of these algorithms are written in the Western [[notation]], where a lowercase letter means a double-layer turn and rotations are denoted by x, y, and z.

Click on an algorithm (not the camera icon) to watch an animation of it.

==Permutations of Edges Only==
This subgroup, '''EPLL''' is used as a [[sub step]] for many speedsolving methods, for example in the [[VH method]] ([[COLL]]).

===H Permutation===
A.K.A. X-PLL, the case you get if you do U2 on this, a case in the [[CPLL]] group.
