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)$$S_3\times C_3^3:C_3^2.D_4.C_2^3$, of order \(93312\)\(\medspace = 2^{7} \cdot 3^{6} \)
$\operatorname{Aut}(H)$ $(C_3^2\times S_3^2):\SD_{16}$, of order \(5184\)\(\medspace = 2^{6} \cdot 3^{4} \)
$W$$C_3^4:Q_8$, of order \(648\)\(\medspace = 2^{3} \cdot 3^{4} \)
