3x3 · PLL
3x3 PLL T algorithm
3x3 PLL T algorithm: 14 turns, opening with R U R'. Case recognition, the complete sequence, and practical execution notes.
Permute the last-layer pieces while preserving their orientation and the first two layers.
T 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 R; R: B L F; B: R B B; L: L R L. The letters identify colors by their reference faces. Piece locations (position ← home piece): UFR ← UBR, UBR ← UFR, UL ← UR, UR ← UL.

The opening is R U R'; the final segment is U R' F'. This version contains 14 face, wide, or slice turns and no whole-puzzle rotations.
