WebThen G has a unique largest F -free normal subgroup. Proof. Given normal F -free subgroups M and N of G, it su‰ces to show that MN is F -free in G. Let c be the natural G-isomorphism from MN=M to N=ðN V MÞ, and observe that if C=M is an F -cyclic subgroup of G=M with M J C J MN, then cðC=MÞ is an F -cyclic subgroup of G=ðM V NÞ.
