초록

An SQNS-group G is a group in which every proper sub- group of G is either s-quasinormal or self-normalizing and a minimal non-SQNS-group is a group which is not an SQNS-group but all of whose proper subgroups are SQNS-groups. In this note all the finite minimal non-SQNS-groups are determined.

Abstract

An SQNS-group G is a group in which every proper sub- group of G is either s-quasinormal or self-normalizing and a minimal non-SQNS-group is a group which is not an SQNS-group but all of whose proper subgroups are SQNS-groups. In this note all the finite minimal non-SQNS-groups are determined.
