is it possible to put the square-1 together in an unsolvable state?

[AlanAlanine]

someone told me that if you take apart the square-1, you can put it back together with whatever pieces in the top and bottom layers and it will be solvable (unlike the 1/12 chance for rubik's cube). i tried this a few times and it worked, but i was wondering if someone had a better answer.

Yes you should be able to if you put i back together in square state because you have the parity algs. Manually by taking apart and puttinh the puzzle back together. The least amount of pieces you can swap placed are two and you have and alg for that. You cant flip a single edge .
But shape wise i dont know, but I still think you can solve and reach any state thought of. because of the amount of pieces which can be in each layer, it will have to give 360 degrees and as far as I know and remember you can solve all possibly shapes. But im not sure on the last think here, but if any one know better then its something I would like to know too.

It's always solvable.

To elaborate: every cube shape that is possible to make out of 8 corners and 8 edges can be solved. Once you get it into cubeshape, parity is possible and you can do swaps of 2 edges and 2 corners, which means that any permutation of the corners and any permutation of the edges is possible. So if any shape and any permutation of pieces is solvable, any way of putting the pieces together is possible.
