Setup / recognition

Apply this scramble to a solved cube to reach the PLL Ab case so you can practise it on demand:

Perm family: A. You recognise it by the adjacent corner swap — read the headlights, bars and blocks on the side stickers before turning.

About this case

PLL Ab (Ab Permutation) is a PLL case — the permutation step of CFOP. Adjacent Corner Swap. It is performed after OLL has oriented the top face; once this algorithm cycles the pieces into place, the cube is solved.
