PLL

Pll is the last step of the Fridrich method right after Oll. We need to memorize 21 algorithms to permute the last layer correctly. Usually we will do a U,U',U2 to check the Pll patterns before we decide to apply which algorithms.

And the following  one is the diagrams and algorithms.

Pll 01

(R U' R)(U R U R)(U' R' U' R2)

 

Pll 02

(R2' U)(R U R' U')(R' U')(R' U R')

Pll 03

M2 U M2 U2 M2 U M2

Pll 04

(R'U'R) (U'R)(U R U'R')(U R U)(R2 U')(R'U2)

Pll 05

x' R2 D2(R' U' R)D2(R' U R')

 

Pll 06

(l U' R)D2(R' U R)D2 R2

Pll 07

x'(R U' R')D(R U R')u2'(R' U R)D(R' U' R)

Pll 08
