Reorienting the center without changing anything else

Postby Calisme » Mon Sep 05, 2011 2:43 am

I have a 5x5x5 rubik's cube and am making a pattern that, if made with a 3x3x3, the orientation of the center tile wouldn't matter.

Correct:

Incorrect:

I need to rotate the left face, the 3x3x3 center(treated as one tile), counterclockwise. Anyone have any ideas?

Not sure about a 5x5, but with a 3x3, you need to do an even number of 90 degree rotations of the centres. You can rotate one face 180 degrees, 2 faces 180 degrees or 2 faces 90 degrees, but not 1 face 90 degrees.

Rotate U2 centre - (RL U2 R'L' U) x2

Rotate R, R2 or R' AND U', U2 or U - RL' FB' UD' (R, R2 or R') LR' BF' DU' (U' U2 or U). Note that here the direction of rotation of U and R is opposite.
Please take off topic discussion off this forum. Thanks.

I'm guessing that your situation is not what it looks like. You could have a case where similar pieces are switched, but you can't tell. For example, two blue x-centers could be switched. However, since they are both blue, they seem to be in the correct spot. You could try switching pieces with the same color, like x-centers and +-centers. Doing that might lead to a situation that you are familiar with, allowing you to get the cube into the position you want.

Also, redKB on YouTube made this video on how to make the cube in a cube pattern. He shows how to do it on a 5x5x5 as well as other cube sizes.

Hope this helps.

Thanks for your help, Zeotor!

I feel like I lost some of the accomplishment that could be associated with getting into that pattern by just using an algorithm, but my method is plagued by the fact that it is associated with parity errors, which will only allow me to reach reach the solved cube^5 state 25% of the time.

But I got into that state, so thanks for your help.

You can also try commutators, although they ARE quite complicated.
lol, here to help ^_~
