Derived length: $2$

The subgroup is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Ambient group ($G$) information

Description: $\GL(2,11):D_6$
Order: \(158400\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5^{2} \cdot 11 \)
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\times C_6).C_2^5.\PSL(2,11).C_2$
$\operatorname{Aut}(H)$ $C_4\times C_{12}:C_2^4$, of order \(768\)\(\medspace = 2^{8} \cdot 3 \)
$W$$C_2\times D_{12}$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
