X-Git-Tag: 1.3.0~6 X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/catacomb-python/commitdiff_plain/7db83a89024f642d31af0bf619aa8009bec5f4d5?hp=7db83a89024f642d31af0bf619aa8009bec5f4d5 pock.1: Make a less fatuous observation. Of course a has order dividing p - 1 in Z/pZ. This is Lagrange's theorem. It's valuable to observe that a has order dividing n - 1 because this makes the next step, where we deduce the order of t = a^{(n-1)/q}, work. ---
