3x3 · PLL
3x3 PLL Y algorithm
3x3 PLL Y algorithm: 17 turns, opening with F R U'. Case recognition, the complete sequence, and practical execution notes.
Permute the last-layer pieces while preserving their orientation and the first two layers.
Y belongs to the Opp Swap group in PLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL, UBL, UBR. Upper edges with that color facing up: UF, UL, UB, UR. Reading each side’s top row left to right when facing that side gives F: F F B; R: L R R; B: B L F; L: R B L. The letters identify colors by their reference faces. Piece locations (position ← home piece): UFR ← UBL, UBL ← UFR, UL ← UB, UB ← UL.

The opening is F R U'; the final segment is F R F'. This version contains 17 face, wide, or slice turns and no whole-puzzle rotations.
