Subgroup ($H$) information

Description:$C_6.\GL(2,\mathbb{Z}/4)$
Order: \(576\)\(\medspace = 2^{6} \cdot 3^{2} \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $\langle(4,7)(5,6), (4,7)(5,6)(8,9,15,10)(11,14,13,12), (1,2,3), (4,5,7), (8,15) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

The subgroup is nonabelian and monomial (hence solvable).

Ambient group ($G$) information

Description: $D_6.S_4^2$
Order: \(6912\)\(\medspace = 2^{8} \cdot 3^{3} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$4$

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_2^3\times A_4^2.C_2^2\times S_3$
$\operatorname{Aut}(H)$ $C_2^4:D_6^2$, of order \(2304\)\(\medspace = 2^{8} \cdot 3^{2} \)
$W$$\GL(2,\mathbb{Z}/4):D_6$, of order \(1152\)\(\medspace = 2^{7} \cdot 3^{2} \)
