We have seen that if we can show that there is only one Sylow $p$-subgroup for some prime $p$ dividing 56, then this must be a normal subgroup and we are done. Solution. By the Third Sylow Theorem, there are either one or eight Sylow $7$-subgroups. the light boltonWebmodule decomposition (see Lemma 4.5). Therefore, in some cases, the use of Theorem 4.1, instead of its classic form, considerably broadens the range of application.
