We prove that are primitive the finite groups whose normalizers of the Sylow subgroups are primitive. We classify the groups of such class, denoted by , and we study the Schunck classes whose boundary is contained in . We give also necessary and sufficient conditions in order that the projectors be subnormally embedded.
Si prova che sono primitivi i gruppi finiti nei quali siano primitivi i normalizzanti dei sottogruppi di Sylow. Si classificano i gruppi di tale classe, denotata con , e si studiano le classi di Schunck il cui bordo sia contenuto in , fornendo, tra l'altro, condizioni necessarie e sufficienti affinchè i proiettori siano subnormalmente immersi.
