2x2 CLL H 1 algorithm

Solve the final four corners of the 2x2 after completing the first layer.

CLL H 1 belongs to the H group in CLL.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: none. Reading each side’s upper corner stickers left to right when facing that side gives F: R L; R: U U; B: F F; L: U U. The letters identify colors by their reference faces.

Execute the algorithm

F R2 U' R2 U' R2 U R2 F'

The opening is F R2 U'; the final segment is U R2 F'. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
