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: B F; R: R L; B: F B; L: L R. The letters identify colors by their reference faces.
