Letbe some partition of the set of all primes,Gbe a finite group and. A setof subgroups ofGis said to be acomplete Hall-set ofGif every non-identity member ofis a Hall-subgroup ofandcontains exactly one Hall-subgroup ofGfor every. A subgroupHofGis-permutableinGifGpossesses a complete Hall-setsuch thatHAx=AxHfor alland all. We say that a subgroupHofGisn--embeddedinGif there exists a normal subgroupTofGsuch thatHTis-permutable inGand, whereis the subgroup ofHgenerated by all those subgroups ofHwhich are-permutable inG.In this paper, we study the properties of then--embedded subgroups and use them to determine the structure of finite groups. Some known results are generalized.
