I recently wrote a program that takes an image in TV scan order and puts it in a scan order which approximates the peano curve. This brings up a couple of questions which I don't know enough to solve: Considering images to be of size M = N*N, where N is of the form 2^n, we can think of the transformation to be a permutation "peano(m)" where m = 0,1,...,M - 1. What I am interested in is, given the group of permutations of M elements, what is the order of the permutation peano(m)? How does one find the inverse to this permutation? Are there easy general results regarding finding the inverse of a permutation?
