Webtries with generating sets of permutation groups with highly e cient product replacement algorithms. The link between model symmetries and polynomial mixing times of orbital Markov chains is established via a path coupling argument that is constructed so as to make the coupled chains coalesce whenever their respective WebAbstract. We study a class of recursive permutation generation methods which construct a sequence of all n! permutations of n elements by repeatedly generating all permutations of the elements in the first n −1 positions and exchanging one of them with the element in the n -th position. We give a general principle which enables us to obtain a ...
