3x3 · 1LLL
3x3 1LLL 40 51 algorithm
3x3 1LLL 40 51 algorithm: 19 turns, opening with U2 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: UFR, UBL. Upper edges with that color facing up: UL, UR. Reading each side’s top row left to right when facing that side gives F: B U F; R: R B B; B: U U L; L: F R U. The letters identify colors by their reference faces.
Execute the algorithm
U2 R U' R' U2 R U' R' U R U' R' F' U F U' R U R'
The opening is U2 R U'; the final segment is R U R'. This version contains 19 face, wide, or slice turns and no whole-puzzle rotations.
