Minimum moves on Rubik's Cube

[finlip]

Imagine a Rubik's cube that is fixed in space. Do we need all six moves; R, L, F, B, U, and D; to get every possible state of the cube? Or are any of these moves redundant?

For example, can some sequence of R, L, F, B, and U be equivalent to D?

Too bad no one answered my inquisitive question. What a shame! I was so happy when I saw this forum. I thought all my questions would be answered here.

D=L R F2 B2 L' R' U L R F2 B2 L' R'

Also notice how robots like the gan robot don't have an 'arm' connected to the upper center, meaning they always solve the cube without U moves.

Yes, you can see https://github.com/hkociemba/RubiksCube-TwophaseSolverFiveFaces for reference.

too bad you werent patient

If I had been more patient, I may have had no replies. See how many replies I got after my second post which was ten days after the first.

Seems I didn’t look into the forum for quite a while, that’s the reason for my late response. I just wanted to mention that I wrote a solver in Python a few years ago which uses only 5 faces and solves the cube in less than 22 moves on average.Look here for details eventually.

Atleast 1 move

The rules are clear:

3.13 - If no one answer you thread, just bump it lol

Sometimes posts just fly under the radar, bumping them often helps.
Considering OP hasn't been onlinr since their last post, this seems to not make a difference anyway.
