Metahamiltonian groups and related topics [PDF]
A group is called metahamiltonian if all its non-abelian subgroups are normal. This aim of this paper is to provide an updated survey of researches concerning certain classes of generalized metahamiltonian groups, in various contexts, and to prove some ...

On the Structure of Groups whose Non-Abelian Subgroups are Serial [PDF]
Necessary and sufficient conditions are given for a locally finite group to have all non-abelian subgroups serial. We also obtain results for groups whose non-abelian subgroups are permutable.

A Classification of Finite Metahamiltonian p-Groups [PDF]
A finite non-abelian group \(G\) is called metahamiltonian if every subgroup of \(G\) is either abelian or normal in \(G\). If every subgroup of \(G\) is normal in \(G\), then \(G\) is called Hamiltonian and such groups were classified by \textit{R. Dedekind} [Math. Ann. 48, 548--561 (1897; JFM 28.0129.03)]. If every proper subgroup of \(G\) is abelian,

Finite metahamiltonian p-groups
The paper under review contains a series of results about metahamiltonian \(p\)-groups, which are then used by X. G. Fang and the first author to classify these group in a paper in preparation. A non-abelian group is said to be Hamiltonian if all of its subgroups are normal, and metahamiltonian if all of its non-abelian subgroups are normal. The latter

On metahamiltonian groups of infinite rank
A group is metahamiltonian if all its non-Abelian subgroups are normal. The authors continue their research on the influence of the subgroups of infinite rank on the group's structure. In the article, they prove that a generalized soluble group of infinite rank is metahamiltonian if and only if all its subgroups of infinite rank are either Abelian or ...

On groups that are nearly metahamiltonian
We consider groups whose subgroups are either normal or have Chernikov commutant. It was proved that if such group G has a subgroup H of finite index and its commutant is a Chernikov group, then commutant of group G is a Chernikov group.

The Classification of Finite Metahamiltonian $p$-Groups
A group is called metahamiltonian if all non-abelian subgroups of it are normal. This concept is a natural generation of Hamiltonian groups. In this paper, a complete classification of finite metahamiltonian $p$-groups is given.

A note on locally graded minimal non-metahamiltonian groups
Summary: We prove that a nonperfect locally graded minimal non-metahamiltonian group \(G\) is a soluble group with derived length of at most 4. On the other hand, if \(G\) is perfect, then \(G/\Phi (G)\) is isomorphic to \(A_{5}\), where \(\Phi (G)\) is the Frattini subgroup of \(G\) and \(A_{5}\) is the alternating group.
