A subgroupHof a finite groupGis said to satisfy Π-property inGif for every chief factorL/KofG, |G/K:NG/K(HK/K∩L/K)| is a π(HK/K∩L/K)-number. A subgroupHofGis called Π-supplemented inGif there exists a subgroupTofGsuch thatG=HTandH∩T≤I≤H, whereIsatisfies Π-property inG. In this article, we investigate the structure of a finite groupGunder the assumption that some primary subgroups ofGare Π-supplemented inG. The main result we proved improves a large number of earlier results.
