Subgroup ($H$) information

Description:$C_6^2.D_4$
Order: \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
Index: \(5\)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)

Derived length: $3$

The subgroup is maximal, nonabelian, a Hall subgroup, and monomial (hence solvable).

Ambient group ($G$) information

Description: $D_{10}.\SOPlus(4,2)$
Order: \(1440\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

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 $W = N_G(H) / Z_G(H)$.
