Bolado Caballero, Ana; Martínez Verduch, José Injectors in \({\mathcal F}.{\mathcal S}\)-groups and nilpotent subgroups of their solvable sections. (English) Zbl 0715.20021 Bull. Soc. Math. Belg., Sér. B 43, No. 1, 113-115 (1991). The authors observe that some elementary properties of F-injectors for Fitting classes F can be extended from finite soluble groups to groups whose soluble residual belongs to F.
