The structure of metahamiltonian groups

M. Brescia, M. Ferrara, M. Trombetti

Abstract: A group is called metahamiltonian if all its non-abelian subgroups are normal. The aim of this paper is to provide an exhaustive but self-contained reference to the structure of metahamiltonian groups fixing several relevant mistakes appearing in the literature.
