Conjecture that the automorphism group of a non-cyclic group of prime power order is always bigger

This article describes an open problem in the following area of/related to group theory: p-groups

Statement

Let p be a prime and G be a non-cyclic p-group; in other words, G is a group of prime power order. The conjecture states that the order of the automorphism group \operatorname{Aut}(G) is at least equal to the order of G.
