- A *must* see video on how to quickly recognizes the PLL based on features like headlights, bar, pairs...
The 21 PLL cases
Source: http://www.cubewhiz.com/pll.php
Corners Only
Edges Only
Swapping Two Adjacent Corners & Two Edges
Cycling Three Corners & Three Edges
To recognize these PLLs:
- Put the HEADLIGHT on the left
- Observe the position of the BLOCK: if it is as the FRONT (resp. FAR RIGHT, BACK and CLOSE RIGHT), then it is a Ga (resp. Gb, Gc and Gd) permutation.
To remember the algorithms, observe the sequence of RIGHT face versus sequence of UP face:
- Ga:
R2 R' R' R
vsUw U U' Uw'
- Gb:
R2 R' R R
vsUw U U' Uw'
- Gc:
R2' R R R'
vsUw' U' U Uw
- Gd:
R2' R R' R'
vsUw' U' U Uw
