Abstract

We study the set G[k] of kth powers in finite groups G. We prove that if G[12] is a subgroup, then G must be soluble; moreover, 12 is the minimal number with this property. The proof relies on results of independent interest, classifying almost simple groups G and positive integers k for which G[k] contains the socle of G.
