The S-permutability of some p-subgroups of O^p(G)plays an important role. Some known results can be reproved and some others appear as corollaries of our main theorems.Reserva de todos los derechosFinite groupP-supersoluble groupS-semipermutable subgroupMATEMATICA APLICADAArtículo10.1007/s00605-016-0987-9Abierto
