3x3 COLL T 5 algorithm

Solve the last-layer corners with the last-layer edges already oriented; edge permutation may remain.

T 5 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: F R; R: B U; B: B R; L: U L. The letters identify colors by their reference faces.

y' Rw U R' U' Rw' F R F'

The opening is y' Rw U; the final segment is F R F'. This version contains 8 face, wide, or slice turns and 1 whole-puzzle rotation.
