3x3 1LLL 8 37 algorithm
3x3 1LLL 8 37 algorithm: 15 turns, opening with y2 R U2. 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: UFL. Upper edges with that color facing up: UF, UR. Reading each side’s top row left to right when facing that side gives F: B R F; R: U B L; B: U U R; L: U U R. The letters identify colors by their reference faces.

y2 R U2 R B' R' B R' U2 R U' R' U R U' R'
The opening is y2 R U2; the final segment is R U' R'. This version contains 15 face, wide, or slice turns and 1 whole-puzzle rotation.
