The existance of the M-theory dimensions is demanded by the mathematics. M-theory is .. a bit immature still. I haven't heard of any observeable hard predictions coming out of M-theory yet.
The 3 large space dimensions seem to be interchangeable, and time seems to be different. What order we place them in is arbitrary. So, the 1st dimension is any dimension.
Augi, I believe there are N-dimensional tic-tac-toe and rubic-cube games on the internet.
