3x3 PLL Rb algorithm
3x3 PLL Rb algorithm: 13 turns, opening with R' U2 R. Case recognition, the complete sequence, and practical execution notes.
Permute the last-layer pieces while preserving their orientation and the first two layers.
Rb 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: L F L; R: F L R; B: B R F; L: R B B. The letters identify colors by their reference faces. Piece locations (position ← home piece): UFR ← UFL, UFL ← UBL, UBL ← UFR, UL ← UB, UB ← UR, UR ← UL.

R' U2 R U2 R' F R U R' U' R' F' R2
The opening is R' U2 R; the final segment is R' F' R2. This version contains 13 face, wide, or slice turns and no whole-puzzle rotations.
