FINITE
$p$-GROUPS WITH SMALL AUTOMORPHISM GROUP
Published online by Cambridge University Press: 20 April 2015
Abstract
For each prime $p$ we construct a family
$\{G_{i}\}$ of finite
$p$-groups such that
$|\text{Aut}(G_{i})|/|G_{i}|$ tends to zero as
$i$ tends to infinity. This disproves a well-known conjecture that
$|G|$ divides
$|\text{Aut}(G)|$ for every nonabelian finite
$p$-group
$G$.
