The ambient group is nonabelian and nonsolvable.

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_6^2.D_4$, of order \(4147200\)\(\medspace = 2^{11} \cdot 3^{4} \cdot 5^{2} \)
$\operatorname{Aut}(H)$ $S_5\times S_6:C_2$, of order \(172800\)\(\medspace = 2^{8} \cdot 3^{3} \cdot 5^{2} \)
$W$$\PGL(2,9):S_5$, of order \(86400\)\(\medspace = 2^{7} \cdot 3^{3} \cdot 5^{2} \)
