A Perm
PLL Ab — Ab Permutation
Adjacent Corner Swap.
Algorithm
x'RU'RD2R'URD2R2x
11 moves. Execute with the cube already oriented (top face one colour) and the last layer on top.
Setup / recognition
Apply this scramble to a solved cube to reach the PLL Ab case so you can practise it on demand:
z2x'R2D2R'U'RD2R'UR'x
Perm family: A. You recognise it by the adjacent corner swap — read the headlights, bars and blocks on the side stickers before turning.
