Abstract

Define a random variable ξn by choosing a conjugacy class C of the Sylow p-subgroup of Spn by random, and let ξn be the logarithm of the order of an element in C. We show that ξn has bounded variance and mean order log n /log p +O(1), which differs greatly from the average order of elements chosen with equal probability.
