The Java program written by Landon Kryger (GuiltyBystander) is linked from this post: http://twistypuzzles.com/forum/viewtopic.php?f=1&t=22353 http://twistypuzzles.com/forum/viewtopic.php?f=1&t=22353

Here’s my note about my terminology and steps:

Ten types of pieces and my terminology:

- Core: reference
- Face: U
- Edge: UF
- [UD]
- [UDF]: 3.1.32 inner edge
- Corner [UFR]
- Inverted Edge [UDFR]: 3.1.31 inner edge
- [UDLR] = [UD]^-1: 3.1.32 centers
- Inverted Face [UDLRF]: 3.1.31 centers
- Inverted Core [UDLRFB]

Steps

- Use core as reference. ( -U,-F2 )
- Rotate faces, trivial. [UD] pieces are automatically solved.
- Solve edges. (use 1 layer view)
- Solve corners. just like rubik’s cube (use 1 layer view). Now, core, face, edge, [UD], corners are solved.
- Solve inv core
- Solve inv face. At the same time, [UDLF] will be solved automatically.
- solve [UDF] (2 layers circle)

- solve inv edges (view: 2 layers)

I have a screenshot of my first solve. It took 3191 steps. I also used long commutators or repetitions to solve certain types and didn’t optimize for move count.

After solving the complex 3x3x3, I used that program to played a variation where I generated a scramble by some 180 deg turns, and try to solve using only 180 deg turns. That’s a different puzzle and requires new algorithms. I recommend you to try it.

Here’s a scramble sequence if you like to use:

F2,U2,R2,D2,L2,B2,U2,B2,R2,F2,R2,D2,B2,R2,F2,R2,F2,R2,D2,F2,R2,F2,R2,U2,B2,L2,F2,D2,B2,R2,B2,D2,F2,R2,U2,R2,F2,L2,F2,D2,F2,U2,F2,U2,F2,D2,F2,L2,U2,L2,B2,R2,D2,B2,U2,B2,R2,U2,F2,L2,F2,U2,R2,B2,L2,B2,D2,R2,U2,B2,U2,B2,R2,D2,F2,U2,F2,D2,L2,U2,L2,B2,D2,R2,F2,R2,U2,B2,D2,B2,D2,R2,U2,R2,U2,R2,B2,U2,R2,U2,
