Subgroup ($H$) information

Description:$C_3^2:C_4$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Index: \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(1,4)(2,6), (1,2,4,5)(3,6)(7,9)(10,12)(13,15), (1,3,4)(2,6,5), (2,5,6)\rangle$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, monomial (hence solvable), metabelian, and an A-group.

Ambient group ($G$) information

Description: $C_3^4:(D_4\times \GL(2,3))$
Order: \(31104\)\(\medspace = 2^{7} \cdot 3^{5} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$5$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

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.C_6.D_4.C_2$, of order \(62208\)\(\medspace = 2^{8} \cdot 3^{5} \)
$\operatorname{Aut}(H)$ $F_9:C_2$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
$W$$\SOPlus(4,2)$, of order \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
