The final step of CFOP, Permutation of the Last Layer, commonly known as PLL, consists of 21 algorithms that rearrange or permute, oriented edges and corners in the last layer. In order for CFOP solvers to progress their times, it is important for them to be able to recognize and quickly execute all 21 cases.

Unlike OLL, each PLL case has its own letter name. PLLs are recognized by looking at a number of aspects

  • Headlights
    • PLLs, especially the four G perms, can have two matching corner sticker colors on a side. These are very easy and important to recognize, as they can help determine any U move adjustments before the PLL has to be executed
  • Blocks
    • PLL can have two or three piece long "blocks" where one of the four colors are arranged together. This in combination with headlights are how most cubers recognize these PLLs
  • Other Matching Colors
    • For recognizing some PLL such as E Perm
  • Prediction from OLL
    • Certain OLLs permute pieces, in some case solving both orientation of corners and edges and permutation of corners and/or edges.
