2x2 CLL Sune 4 algorithm

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

CLL Sune 4 belongs to the Sune group in CLL.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: UFL. Reading each side’s upper corner stickers left to right when facing that side gives F: R U; R: B U; B: R U; L: L F. The letters identify colors by their reference faces.

Execute the algorithm

F R' F' R U2 R U2 R'

The opening is F R' F'; the final segment is R U2 R'. This version contains 8 face, wide, or slice turns and no whole-puzzle rotations.
