Addendum: Could you tell how did you generate your single
cycle permutations? I like to apply the same methodology
in order to avoid having differences in generation methods
eventually create sort of 'bias' (artefacts) in the results
of comparison between the effects of arbitrary and single-cycle
permutations on the quality of S-boxes. Thanks.
