PLL A perm

1. Aa perm:

(x L2) D2′ (L’ U’ L) D2′ (L’ U L’ x’) (a headlight on L-face)

(x R’ U R’) D2 (R U’ R’) D2 (R2 x’) (V mark on front left position)

2. Ab perm:

(x’ L2′) D2′ (L U L’) D2′ (L U’ L x) (a headlight on L-face)

(x R2′) D2 (R U R’) D2 (R U’ R x’) (V mark on front left position)

The idea to use 2 algorithms each is to minimize time for AUF before PLL process. You will find a headlight by 75% chance and complete V mark 50% after OLL. And in half of the cases, you don’t need AUF before PLL process.

There is much similarity in algorithm one and another, so if you want to avoid AUF completely, just memorize the following 2 more each.

Aa perm (additional):

(x’ L’ U L’) D2′ (L U’ L’) D2′ (L2 x) (a headlight on F-face)

(x’ R2) D2 (R’ U’ R) D2 (R’ U R’ x) (a headlight on R-face)

Ab perm (additional):

(x’ R U’ R) D2 (R’ U R) D2 (R2′ x) (a headlight on F-face)

(x L U’ L) D2′ (L’ U L) D2′ (L2′ x’) (V mark on front right position)

It is necessary to regrip and rotate the cube at the beginning for all the cases. The following tips may help you.

1) which hand to regrip? -> the hand of the side of V mark.

2) which side to rotate first, x or x’? -> if V mark is front side, then x, and if not, then x’.
