2x2 CLL Sune 2 algorithm

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

CLL Sune 2 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: F U; R: B U; B: F U; L: R L. The letters identify colors by their reference faces.

Execute the algorithm

R U R' U' R' F R F' R U R' U R U2 R'

The opening is R U R'; the final segment is R U2 R'. This version contains 15 face, wide, or slice turns and no whole-puzzle rotations.
