The groups G considered in this paper have the property that every normal nonsupersoluble subgroup of G has a finite, G-invariant, nonsupersoluble image. The structure of a certain radical, defined in terms of ascendant supersoluble subgroups, is determined. The main result is a supersolubility criterion for polycyclic groups.doi:10.2307/2159649 fatcat:elzr6os3oneqfpqhsmpb4umepm
