Hi

This is one of the new creation of tony Fisher, it is a combination of a 4x4x4 and a 5x5x5. I solve it like a 4x4x4 and the center like a 5x5x5.

I needed one special move : to swap two edge pieces without effecting the center, this is however 25 turns, Or I need to swap two middle edge center pieces in less.

For a 4x4x4 and a 5x5x5 puzzle master it was easy to solve

From your description it sounds like my (very inefficient) methods for the 4x4x4 and 5x5x5 would avoid the need for such a move. I solve the outer edges first, then painstakingly solve the centers using a three cubie swap. I wonder...

I'm looking forward to playing with this thing!

Do you never run into the orientation parity problem when solving the 4x4? I guess that's what Ton means. It would also explain the 25 moves, since an algorithm for solving the orientation parity of a super 4x4 has been mentioned once or twice in the speedcubing forum and it has 25 moves.

Wow. I can't imagine how it moves. Could you please post some picture of it durring a half-twist?

Thanks

I found the picture it was posted today just in a different topic. Look for Hendrik Haak. He posted the picture.

I would not recommend to solve the outer edge first this since the center 5x5x5 is like a bandage center, no problem when you do the centers first

The two swap edge problem is also on a 5x5x5 but I do this while the puzzle is in a mixed "3x3x3"" state so that tkase 13 moves. However on a 4x4x4 you see this parity problem in the last stages, so I need a bit more moves.

So this puzzle takes ony a few moves more, I gues doing outer edge first would take much more moves

Very interesting puzzle!

How do you mess up the small centre pieces? Can't work it out.

If you would open an eastheen 4x4x4 , you see basicly the same center

Left is a orginal Eastheen 4x4x4

It looks to me like you do it with what would be r l u d f b moves on a 4x4x4. The larger center squares would move like the centers on the 3x3x3.

Anyone who's ordering extras from Tony, please get in touch with me.

BTW if you have an Esatheen, rermove the center caps , now you can see how the centers piecse work on the overhangcube.

As I understand it, it is essentially a 5x5x5 cube, but without the middle set of edges. That is neat, as it brings back the party problems.

There is also the extra complication that it is made from a 4x4x4, so you cannot move the middle layer separately, as it is fixed to three adjacent slices. To look at it another way, three of the internal slices (say the b, l, d slices) don't move. That is why it would be easier to solve centres first, using f, r, u and face turns.

Hello,

Very nice idea, and well done, felicitations !!!

In 4x4x4, you can cut the back of the the edge center and coins and it will not more be attached to the three sides, since the center are apparent, it is not a problem...

Very nice cube really !!!

See you...
