Abstract

A subgroup H of a group G is said to be permutable in G, if HK = KH for every subgroup K of G. Every permutable subgroup is ascendant, but, in general, the converse is far from being true. In this paper we characterize some infinite groups whose ascendant subgroups are permutable in terms of their Sylow structure.
