3x3 COLL T 6 algorithm
3x3 COLL T 6 algorithm: 11 turns, opening with R' U R2. Case recognition, the complete sequence, and practical execution notes.
Solve the last-layer corners with the last-layer edges already oriented; edge permutation may remain.
T 6 belongs to the T group in COLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL. Upper edges with that color facing up: UF, UL, UB, UR. Reading each side’s upper corner stickers left to right when facing that side gives F: R L; R: F U; B: B B; L: U F. The letters identify colors by their reference faces.

The opening is R' U R2; the final segment is R2 U' R. This version contains 11 face, wide, or slice turns and no whole-puzzle rotations.
