3x3 ELL Pure 4 Flip algorithm
3x3 ELL Pure 4 Flip algorithm: 11 turns, opening with M' U2 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: none. Reading each side’s top row left to right when facing that side gives F: L U L; R: F U F; B: R U R; L: B U B. The letters identify colors by their reference faces.
Execute the algorithm
M' U2 M U2 M' U M U2 M' U2 M
The opening is M' U2 M; the final segment is M' U2 M. This version contains 11 face, wide, or slice turns and no whole-puzzle rotations.
