3x3 · PLL
3x3 PLL E algorithm
3x3 PLL E algorithm: 16 turns, opening with y x' R. Case recognition, the complete sequence, and practical execution notes.
Permute the last-layer pieces while preserving their orientation and the first two layers.
E 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: R F L; R: F R B; B: L B R; L: B L F. The letters identify colors by their reference faces. Piece locations (position ← home piece): UFR ← UFL, UFL ← UFR, UBL ← UBR, UBR ← UBL.

The opening is y x' R; the final segment is R' D' x. This version contains 16 face, wide, or slice turns and 3 whole-puzzle rotations.
