  • Let $G$ be a group with all subgroups subnormal. A normal subgroup $N$ of $G$ is said to be $G$-minimax if it has a finite $G$-invariant series whose factors are abelian and satisfy either $\max$-$G$ or $\min$-$G$. It is proved that if the normal closure of every element of $G$ is $G$-minimax then $G$ is nilpotent and the normal closure of every element is minimax. Further results of this type are also obtained.
