Subgroup ($H$) information

Description:$C_3^2:D_6\times S_4$
Order: \(2592\)\(\medspace = 2^{5} \cdot 3^{4} \)
Index: \(7\)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(1,2)(5,6)(8,12,9)(10,13,11)(14,15,16)(17,18), (4,7)(5,6)(8,13,14)(9,10,16) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

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

Ambient group ($G$) information

Description: $C_3^2:D_6\times \GL(3,2)$
Order: \(18144\)\(\medspace = 2^{5} \cdot 3^{4} \cdot 7 \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$3$

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)$$C_2\times \SO(3,7)\times \AGL(2,3)$
$\operatorname{Aut}(H)$ $S_4\times \AGL(2,3).C_2^2$
$W$$C_6^2:D_6$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
