Ambient group ($G$) information

Description: $\GL(2,11):D_4$
Order: \(105600\)\(\medspace = 2^{7} \cdot 3 \cdot 5^{2} \cdot 11 \)

Derived length:$2$

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)$$C_2^2.C_2^5.\PSL(2,11).C_2$
$\operatorname{Aut}(H)$ $C_4\times D_4\times S_4$, of order \(768\)\(\medspace = 2^{8} \cdot 3 \)
$W$$D_4\times S_4$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \)
