Throughout this paper, all groups are finite andGalways denotes a finite group;is some partition of the set of all primes. A groupGis said to be-primary ifGis a-group for some. A-semiprojector ofGis a subgroupHofGsuch thatHN/Nis a maximal-subgroup ofG/Nfor all normal subgroupsNofG. Let. Then we say thatis a-covering subgroup system for a subgroupHinGif all members of the setare-primary subgroups ofGand for eachwiththere are an indexiand a-semiprojectorUofHsuch that. We study the embedding properties of subgroupsHofGunder the hypothesis thatGhas a-covering subgroup systemsuch thatHpermutes withfor alland. Some well-known results are generalized.
