Permute both oriented layers of the 2x2 in the final Ortega stage.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL, UBL, UBR. Reading each side’s top row left to right when facing that side gives F: F B; R: L R; B: B F; L: R L. The letters identify colors by their reference faces.
Execute the algorithm
R U' R' U' F2 U' R U R' U F2
The opening is R U' R'; the final segment is R' U F2. This version contains 11 face, wide, or slice turns and no whole-puzzle rotations.
