Criterion for π-supersolvability for finite groups

It is proved that the class of finite -supersolvable groups is precisely the class of all finite -solvable groups with the following property: For each maximal subgroup M of a -solvable group G with index p for some p , there exists a cyclic subgroup S of order p ( ) such that G = MS and S commutes with each element of the Sylow system _M of the subgroup M.Translated from Matematicheskie Zametki, vol. 52, No. 1, pp. 57–61, July, 1992.
