Ambient group ($G$) information
| Description: | $\GL(2,11):D_4$ |
| Order: | \(105600\)\(\medspace = 2^{7} \cdot 3 \cdot 5^{2} \cdot 11 \) |
| Exponent: | \(1320\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 11 \) |
| 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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_2^2.C_2^5.\PSL(2,11).C_2$ |
| $\operatorname{Aut}(H)$ | $C_4\times \GL(2,\mathbb{Z}/4):C_2^2$, of order \(1536\)\(\medspace = 2^{9} \cdot 3 \) |
| $W$ | $D_4\times S_4$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \) |
