In a permutation sequence built by means of sub permutations, the transitions between successive permutations are subject to a set of n(n – 1)/2 rules that naturally group into n – 1 matrices with a high degree of regularity. By means of these rules, the sequence can be produced in O(3n!) time and O(n) space. To generate all permutations of a given set one can go for (among other things) a mini...
