3x3 · PLL
3x3 PLL F algorithm
3x3 PLL F algorithm: 18 turns, opening with y 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.
F belongs to the Adj 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 F; R: R L B; B: L B R; L: B R L. The letters identify colors by their reference faces. Piece locations (position ← home piece): UBL ← UBR, UBR ← UBL, UL ← UR, UR ← UL.

The opening is y R' U'; the final segment is R' U R. This version contains 18 face, wide, or slice turns and 1 whole-puzzle rotation.
