3x3 COLL T 3 algorithm
3x3 COLL T 3 algorithm: 8 turns, opening with y R' F'. 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 3 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: L F; R: R U; B: L B; L: U B. The letters identify colors by their reference faces.
Execute the algorithm
y R' F' Rw U R U' Rw' F
The opening is y R' F'; the final segment is U' Rw' F. This version contains 8 face, wide, or slice turns and 1 whole-puzzle rotation.
