The structure of metahamiltonian groups

Japanese Journal of Mathematics, 2023
A group is called metahamiltonian if all its non-abelian subgroups are normal. The aim of this paper is to provide an exhaustive and self-contained reference to the structure of metahamiltonian groups. Moreover, the authors fix some relevant mistakes appearing in the literature.

GROUPS WHOSE NONNORMAL SUBGROUPS ARE METAHAMILTONIAN

Bulletin of the Australian Mathematical Society, 2019
If $\mathfrak{X}$ is a class of groups, we define a sequence $\mathfrak{X}_{1},\mathfrak{X}_{2},\ldots ,\mathfrak{X}_{k},\ldots$ of group classes by putting $\mathfrak{X}_{1}=\mathfrak{X}$ and choosing $\mathfrak{X}_{k+1}$ as the class of all groups whose nonnormal subgroups belong to $\mathfrak{X}_{k}$. In particular, if $\mathfrak{A}$ is the class of

Groups Whose Finite Homomorphic Images are Metahamiltonian

Communications in Algebra, 2009
A group G is metahamiltonian if all its non-abelian subgroups are normal. It is proved here that a finitely generated soluble group is metahamiltonian if and only if all its finite homomorphic images are metahamiltonian; the behaviour of soluble minimax groups with metahamiltonian finite homomorphic images is also investigated.

Structure of solvable nonnilpotent metahamiltonian groups

Mathematical Notes of the Academy of Sciences of the USSR, 1983
A group is called metahamiltonian if any nonabelian subgroup of it is invariant. A complete description of the structure of solvable nonnilpotent metahamiltonian groups is given. This improves results of \textit{V. T. Nagrebetskij} [Mat. Zap. 6, No.1, 80-88 (1967; Zbl 0315.20022)].

Structure of periodic nonabelian metahamiltonian groups with an elementary commutator subgroup of rank three

Ukrainian Mathematical Journal, 1989
A group is said to be metahamiltonian if every nonabelian subgroup in it is invariant. The main theorem provides a complete description of periodic metabelian metahamiltonian groups with an elementary commutator subgroup of rank three.

Structure of periodic metabelian metahamiltonian groups with a nonelementary commutator subgroup

Ukrainian Mathematical Journal, 1987
Metahamiltonian groups, i.e., groups in which each nonabelian subgroup is invariant, are a natural generalization of Hamiltonian groups. The present article describes the structure of periodic metabelian metahamiltonian groups with a nonelementary commutator subgroup. It turns out that there exist four types of such groups.
