The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_7^4.C_2^3.(C_6\times S_4)$, of order \(2765952\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 7^{4} \)
$\operatorname{Aut}(H)$ $C_7^3.A_4.C_6^2.C_2$
$W$$D_7^3:D_6$, of order \(32928\)\(\medspace = 2^{5} \cdot 3 \cdot 7^{3} \)
