WebJun 13, 2024 · This group of order $21$ must have a unique Sylow-7 subgroup, so there is only $1$ such mapping (up to isomorphism), leading to one nonabelian group of order 56 where its Sylow-7 subgroup is not normal.

Suppose n 5 = 56 , then there exists a subgroup of G with this order and this with index 280 56 = 5 (namely, any Sylow 5 -subgroup's normalizer). But then the action of G on this subgroup's left cosets (i.e., the regular left action) renders a homomorphism G → S 5 which, if G is simple, must be injective.
