Permutation of the Last Layer is 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 algorithms for each one.

Social Link. Postage and Packaging. What is Fridrich? Why the CFOP in the title? Fridrich method was invented by Jessica Fridrich of Czech Republic in the 's. In part due to Fridrich's publication of the method on her website in , CFOP has been the most dominant 3x3 speedcubing method since around , with it and its variants used by the vast majority of the top speedcubers.
In particular, every speedcuber ranked in the top 10 by 3x3 average at any point since has used a variant of CFOP. All of the worlds best use a variant of this method, apart from selected few that uses Roux. This method is for people who can solve the rubik's cube, hopefully using the beginner layer by layer method, and want to get faster and serious about speedcubing. This could be done in less than 6 moves most of the time.
More explained below. Your aim is to make all yellow sides face up. There are 57 algorithms. You permute move the pieces on the last layer to solve the entire cube. This is completely intuitive, and is probably the hardest part in this method. Having said that, you can still with a bit of practice, see the best cross solution in 15 seconds and execute it in well under 3 seconds.
In fact, sub-2 cross is not even that hard. All cross can be solved in 7 moves, and a big majority of them only need 6 moves. However, you will need to spend a decent amount of time practising this step and the best way to do it is to solve it blindfolded.
Take as long as you want to plan out your cross and solve it blindfolded. You should now decide whether you want to be colour neutral or, well, not colour neutral. This is explained further in the link below. If you're still confused, take the picture to my left. This is fairly intuitive and easy so you should find all four pairs this way. Now we solve both pieces at the same time.
This is the major difference between F2L and Layer by layer. You can learn to do this intuitively, which is not as hard as it seems. Or you can use algorithms. Don't worry if you don't want learn all that yet.
This is what 2-look is for. You solve a cross on top. Then you do the corners. This is highly recommended and you should learn this before you learn PLL. Using 2-look you can get sub easily so don't feel you have to learn all the 57 algorithms yet. Well, there are 57 algorithms and that is quite a lot. Do not feel you have to learn this straight away. Even experienced cubers don't learn this for years. Just take your time.
PLL Permutation of the Last Layer is where y ou permute move the pieces on the last layer to solve the entire cube. There are 21 algorithms. I highly recommend learning this before you learn full OLL. You can also do this in 2-Look. But I don't recommend it because it is significantly slower than full PLL.
Permuting The Last Layer
This method was first developed in the early s combining innovations by a number of speed cubers. Czech speedcuber and the namesake of the method Jessica Fridrich is generally credited for popularizing it by publishing it online in The method works on a layer-by-layer system, first solving a cross typically on the bottom, continuing to solve the first two layers F2L , orienting the last layer OLL , and finally permuting the last layer PLL. Basic layer-by-layer methods were among the first to arise during the early s cube craze. David Singmaster published a layer-based solution in which proposed the use of a cross. The major innovation of CFOP over beginner methods is its use of F2L, which solves the first two layers simultaneously. This step was not invented by Jessica Fridrich.
PLL is the last step of the Fridrich Method. After you finish OLL, pieces on the last layer will need to be permuted moved around. Find out which diagram indicates how you need to move them around, and apply the algorithm. Then one of the diagrams should match what you have. You need all of the 21 algorithms below to solve this stage in a single step. However, if you are willing to do it in two steps instead, you can use what is called the 2look PLL.
