3x3 ELL Pure Opp algorithm
3x3 ELL Pure Opp algorithm: 11 turns, opening with M' U M'. Case recognition, the complete sequence, and practical execution notes.
Resolve the orientation and permutation of the last-layer edges after the corners have been solved.
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: UL, UR. Reading each side’s top row left to right when facing that side gives F: B U B; R: L L L; B: F U F; L: R R R. The letters identify colors by their reference faces.
Execute the algorithm
M' U M' U M' U2 M U M U M
The opening is M' U M'; the final segment is M U M. This version contains 11 face, wide, or slice turns and no whole-puzzle rotations.
