M is the middle (vertical) slice going through the centres F, B, D and U. I'm not sure which is M and Mi (or M' as I call it). I normally call M a rotation so the F centre is rotated until it is on the U face.

Borg rotating like that is called x in WCA notation, I think. M would be to rotate that middle slice in the same direction as L.
lol, here to help ^_~

In the algorithm that I just gave, M is a move of the Middle layer (between R and L), in the same direction as an L turn. I used M' instead of Mi.

None of this happens on a normal cube, only on the void.

The following image shows what (M U M U M U2)(M' U M' U M' U2) does.

just take out the pieces and put them in the original position for god's sake!

Have you seen a void? It's not like a cube. Even if I could ever get one back together again, I don't think it would ever be the same. :)

But you can't seriously believe that the Rubik's folks will never come up with an instruction manual for solving a void... I sure hope not at least.

Thanks so much... I'm wondering if the first solution is all I need? OK, time to get the void parity error again and if it's not one of these two I'll come back and ask again. Thanks SO much for the help. :)

No problem.

Only the first solution is needed for the void cube. The other one is a regular 3x3x3 situation.

To see that they work, click the play/triangle button on the following pages. They will show the solutions being performed.

F2 U' F2 U F2 U' M U F2 U2 M U M' F2 U F2
With this one, only the two edges and four centers are affected. The Void Cube doesn't have centers. So, only the two edges are moved.

(M U M U M U2)(M' U M' U M' U2)
This one only affects the two edges; nothing else is changed. This shows that just two edges can be flipped on a normal Rubik's cube. Since it can happen on a traditional 3x3x3 (and it doesn't involve centers), it can happen on a Void Cube.

Middle slice, between L and R

A shorter alg that is also a top layer destroyer.

M2' U M' U' M2'

Fixes void cube parity but changes around and misorients all the upper layer edges while leaving the corners alone.
