Suppose the front layer F, the back layer B, the right layer R, the left layer L, the upper layer U, and the lower layer D
1. Return the bottom corner:
2-1: R-U-R'
2-2: F'-U'-F
Use formula 2-1 twice, and then use formula 2-2 twice;
2. Usage of T-shape:
Turn T 90 degrees clockwise, 1 with the two corner blocks on the left, and turn the edge block up: front left - upper right - upper left - Lower right - Upper right - Right right.

Other reduction formulas for the third-order Rubik's Cube:
Tank formula 1:
The gun barrel is to the left and has no top on the right Block missing:
Top right - top left - bottom right - top left - top right - top left left - bottom right - top left - top right - bottom right - top right - top right - top right - bottom left.
Tank formula 2:
Turn the gun barrel to the left, and turn the missing piece on the top upward:
Upper left - upper right - lower left - upper right - upper left - Top right - bottom left - top right - top left left - bottom right - top - right - top right - top right - bottom right.
Middle edge return:
3-1: (U'-F'-U-F) (U-R-U'-R')-
3 -2: (U-R-U'-R') (U'-F'-U-F)-
Use formula 3-1, U2, and then formula 3-1, or use formula 3-2 , U2, then use formula 3-2;
Top edge return:
4-1: F (R-U-R'-U') F'
< p>Use formula 4-1 and U twice, and then add formula 4-1 twice;Vertex corner return:
5-1: (R-U'2 -R')U'(R-U'-R')
Use formula 5-1 twice.
