3x3 ELL BF H algorithm
3x3 ELL BF H algorithm: 15 turns, opening with R' U2 R. 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: F U F; R: R L R; B: B U B; L: L R L. The letters identify colors by their reference faces.
Execute the algorithm
R' U2 R U' R' U' R' F R2 U R' U' R' F' R2
The opening is R' U2 R; the final segment is R' F' R2. This version contains 15 face, wide, or slice turns and no whole-puzzle rotations.
