3x3 CMLL L Diagonal algorithm
3x3 CMLL L Diagonal algorithm: 10 turns, opening with U2 R U2. Case recognition, the complete sequence, and practical execution notes.
Solve the four upper corners in Roux after building both side blocks; the remaining edges are solved later.
L Diagonal belongs to the L group in CMLL.
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, UB. Reading each side’s upper corner stickers left to right when facing that side gives F: F L; R: F L; B: U R; L: B U. The letters identify colors by their reference faces.

The opening is U2 R U2; the final segment is R U2 R'. This version contains 10 face, wide, or slice turns and no whole-puzzle rotations.
