### Unexplained Occurence on 11x11 Cube

I've worked my way up through the cubes, 2x2, 3x3, 4x4 and so on, all the way up to the 11x11. I have no problem solving any cube except for the 11x11. Let me explain.

The 11x11 puzzle at the very end, when it's almost completely solved, always ends up with 2 edges that need swapping. The edges are either opposite or adjacent to each other, just like what happens on an even-numbered cube.

In the end I'm left with an entirely solved cube except for these 2 remaining edges that need swapping. I can easily solve this dilemma on the even-numbered puzzles (ie. 4x4, 6x6, 8x8).

I wish someone could explain to me why this happens on the 11x11. Has this ever happened to you? What I'm really looking for is an algorithm to help me so that I can finally solve this.

If you reduced the 11x11 to a 3x3, I think that it's impossible to have just two edge groups swapped. An brief explanation of why this is can be found in the first four minutes of this video.

If you are referring to some other situation, the information in this video may help.

The above shows what my 11x11 looks like at the end with 2 adjacent edges that need to swap places. Other times they are opposite to each other. The entire cube is solved except for these 2 edges that you see. This has been the case every single time when solving it without exception.

A mystery to me...

### Re: Unexplained Occurence on 11x11 Cube

I don't think that the image is displaying properly. Anyway, has the puzzle ever been in a solved state? Also, have any pieces ever popped out? I'm thinking that the cube is in an unsolvable state, since this happens every time. Maybe some pieces came out and were put back in incorrectly.

I think that you should disassemble the cube and put it together solved. If you do that, you will most likely never encounter this problem again.

### Re: Unexplained Occurence on 11x11 Cube

I don't think it's a good idea to take apart the whole 11x11. Solve as much as you can, then take a proper picture (because I can't see the one you posted)
Maybe then you can start disassembling any remaining pieces that can't be solved (unless it's the corners cuz that means you'll have to disassemble a lot)
lol, here to help ^_~

That's what I meant. Probably only the pieces of one layer will need to be rearranged.

I re-stickered those 2 edges and then scrambled the cube. This evening, for the first time since I got it in April, I've solved it completely.

5x5 parity is solved in the Solutions board. Look there. If you can solve 4x4 and 5x5 parity, you should be able to solve any cube parity, but you only need to be able to solve a 5x5 to solve odd numbered puzzles.
Please take off topic discussion off this forum. Thanks.
