Most permutations power to a cycle of small prime length

Group Theory 2023-06-22 v4

Abstract

We prove that most permutations of degree nn have some power which is a cycle of prime length approximately logn\log n. Explicitly, we show that for nn sufficiently large, the proportion of such elements is at least 15/loglogn1-5/\log\log n with the prime between logn\log n and (logn)loglogn(\log n)^{\log\log n}. The proportion of even permutations with this property is at least 17/loglogn1-7/\log\log n.
