WebApr 11, 2024 · Calendar. Abstract : In joint work with Brendan Mallery (Tufts), we introduce the notion of a "shift-similar" subgroup of the group of permutations of the natural numbers N. The definition makes use of the fact that any cofinite subset of N is canonically bijective with N, and is an analog to the well-known condition of "self-similarity" for ... WebThe generating permutations perm i must be given in disjoint cyclic form, with head Cycles. Properties of a permutation group are typically computed by constructing a strong generating set representation of the group using the Schreier – Sims algorithm.
