3x3 1LLL 7 21 algorithm
3x3 1LLL 7 21 algorithm: 14 turns, opening with y2 R' U'. Case recognition, the complete sequence, and practical execution notes.
Solve this specific last-layer orientation and permutation in one sequence after completing the first two layers.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UBR. Upper edges with that color facing up: UF, UR. Reading each side’s top row left to right when facing that side gives F: L R U; R: B B R; B: B U U; L: F U U. The letters identify colors by their reference faces.

y2 R' U' F' U F R U R' U2 R U R' U R
The opening is y2 R' U'; the final segment is R' U R. This version contains 14 face, wide, or slice turns and 1 whole-puzzle rotation.
