Hi,
I would like to write an article (web page) about parity errors. Currently I´m stuck, because I can not answer following questions. Can you?
- is it correct to say that (in case of Rubik´s cube NxNxN) orientation problem is caused by the fact that those parts, which should be solved by "even number of moves" were in fact solved in "odd number of moves"?
- is permutation problem caused by the fact that some of (in case of Rubik´s cube NxNxN) parts seem to be identical to us (edges (wing edges or whatever they are called), to be more precise)?
- what is the cause of parity error in case of square-1? I would say "odd number of moves" (see above), but it is not orientation problem, it is rather permutation problem - but there are no identical pieces on square-1, are they? Is it possible to „avoid“ parity error in case of square-1 as in case of Rubiks cube by method change (reduction vs cage for example)?
As parity error in case of Rubik´s cube NxNxN is considered a situation which can not be solved by reduction to 3x3x3.
