3x3 OLL 40 algorithm
3x3 OLL 40 algorithm: 9 turns, opening with y R' F. Case recognition, the complete sequence, and practical execution notes.
Orient the last layer after completing F2L; permutation is handled in the next stage.
OLL 40 belongs to the Lightning Shapes group in OLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFL, UBR. Upper edges with that color facing up: UF, UB.
Execute the algorithm
y R' F R U R' U' F' U R
The opening is y R' F; the final segment is F' U R. This version contains 9 face, wide, or slice turns and 1 whole-puzzle rotation.
