Let X, F, X β F, be non-trivial Fitting classes of finite soluble groups such that G X is an X-injector of G for all G β F. Then X is said to be normal in F (F-normal). We show that for a subgroup-closed Fitting class X the collection of all subgroup-closed Fitting classes in which X is normal forms
