3x3 · 1LLL
3x3 1LLL 41 24 algorithm
3x3 1LLL 41 24 algorithm: 13 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: UBL, 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: U R U; R: R F F; B: R U L; L: F U L. The letters identify colors by their reference faces.
Execute the algorithm
y2 R U R' U R U2 R' F R U R' U' F'
The opening is y2 R U; the final segment is R' U' F'. This version contains 13 face, wide, or slice turns and 1 whole-puzzle rotation.
