Subgroup ($H$) information

Description:$C_3^2:C_4\times Q_8$
Order: \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
Index: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(1,2,4,5)(3,6), (1,4)(2,6)(7,11,8,13)(10,15,14,12), (7,13,8,11)(10,12,14,15) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_3^3:C_{12}:\GL(2,3)$
Order: \(15552\)\(\medspace = 2^{6} \cdot 3^{5} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$5$

The ambient group is nonabelian and 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 $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_3:S_3.C_6^2.D_{12}.C_2^2$, of order \(62208\)\(\medspace = 2^{8} \cdot 3^{5} \)
$\operatorname{Aut}(H)$ $F_9:C_2^2\times S_4$, of order \(6912\)\(\medspace = 2^{8} \cdot 3^{3} \)
$W$$C_6^2:D_{12}$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
