6 letters “U” with legs facing outwards. I will give several different algorithms. How are they different? Firstly, the arrangement of letters on the cube, secondly, the direction of movement of the cubes during the execution of the algorithm, and thirdly, the sequence of operations. So, the first group of formulas is a combination of two algorithms given earlier on this page – “BDT” and “points”.
The letters “U” are located with their legs facing outward in a clockwise direction.
The centers move counterclockwise:
(
R Dw D’ F’ U2 F Dw’ D F’ U2 F R’) (
Dw D’ Bw’ B Dw’ D Bw B’).
The inverse formula moves the centers clockwise:
(
R F’ U2 F Dw D’ F’ U2 F Dw’ D R’) (
Bw’ B Dw D’ Bw B’ Dw’ D).
If we invert these two formulas, so to speak, reflect them diagonally passing through the far left corner and the near right corner, then the letters U will be located with their legs outward, but counterclockwise, and the centers will change the direction of rotation to the opposite.
The letters “U” are located with their legs facing out counterclockwise.
The centers move clockwise (inversion of the first formula):
(
F’ Dw’ D R U2 R’ Dw D’ R U2 R’ F) (
Bw’ B Dw D’ Bw B’ Dw’ D).
The inverse formula moves the centers counterclockwise (inverse of the second formula):
(
F’ R U2 R’ Dw’ D R U2 R’ Dw D’ F) (
Dw D’ Bw’ B Dw’ D Bw B’).
The inverse formulas here are not exactly inverse, but since each of the two parts of these formulas is an independent algorithm with cyclic movements of the cubes, the combination of inverse algorithms leads to the same result as if the entire formula were reproduced in reverse (rearrange the parentheses in the inverse formulas, and they will become completely reverse). Repeating any of these algorithms three times solves the cube again.
Here is another group of four formulas that will lead to the same results as the 4 formulas above. This is also a combination of “BDT” and “dots” in other versions.
“U” legs outward clockwise, centers move counterclockwise: (
L’ R’ R’ F’ L’ B’ U B L F R U’ R L) (
R L’ F B’ U D’ R L’) =

Lw L’ Dw’ D Lw’ L Dw D’).
