摘要
A subgroup H of a group G is said to be permutable in G, if HK = KH for every subgroup K of G. 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 (AP-groups). We show that the structure of radical hyperfinite AP-groups behave as that of finite soluble groups in which the relation to be a permutable subgroup is transitive (PT-groups).
