3x3 1LLL 4 1 algorithm

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. Upper edges with that color facing up: none. Reading each side’s top row left to right when facing that side gives F: U U F; R: R U B; B: U U L; L: U U F. The letters identify colors by their reference faces.

Execute the algorithm

R U R' F' U2 F R U' R' F U R U' R' F'

The opening is R U R'; the final segment is U' R' F'. This version contains 15 face, wide, or slice turns and no whole-puzzle rotations.
