In this paper we describe some algorithms to identify permutable and Sylow-permutable subgroups of finite groups, Dedekind and Iwasawa finite groups, and finite T-groups (groups in which normality is transitive), PT-groups ...
A subgroup of a group is said to be normal sensitive in if for every normal subgroup of . In this paper we study locally finite groups whose -subgroups are normal sensitive. We show the connection between these groups and ...
