Abstract

Let AA and GG be finite groups such that AA acts coprimely on GG by automorphisms. We provide a complete classification of a finite group GG in which every maximal AA-invariant subgroup containing the normalizer of some AA-invariant Sylow subgroup is nilpotent. Moreover, we show that both the hypothesis that every maximal AA-invariant subgroup of GG containing the normalizer of some AA-invariant Sylow subgroup is nilpotent and the hypothesis that every non-nilpotent maximal AA-invariant subgroup of GG is normal are equivalent.
