Abstract

A subgroup HH of a group GG is said to be \textit{permutable in GG}, if HK=KHHK = KH for every subgroup KK of GG. A result due to Stonehewer asserts that every permutable subgroup is ascendant although the converse is false. In this paper we study some infinite groups whose ascendant subgroups are permutable (APAP--groups). We show that the structure of radical hyperfinite APAP--groups behave as that of finite soluble groups in which the relation \textit{to be a permutable subgroup} is transitive (PTPT--groups).
