3x3 · PLL
3x3 PLL H algorithm
3x3 PLL H algorithm: 7 turns, opening with M2 U M2. Case recognition, the complete sequence, and practical execution notes.
Permute the last-layer pieces while preserving their orientation and the first two layers.
H belongs to the EPLL 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 B F; R: R L R; B: B F B; L: L R L. The letters identify colors by their reference faces. Piece locations (position ← home piece): UF ← UB, UL ← UR, UB ← UF, UR ← UL.
Execute the algorithm
M2 U M2 U2 M2 U M2
The opening is M2 U M2; the final segment is M2 U M2. This version contains 7 face, wide, or slice turns and no whole-puzzle rotations.
