Subgroup ($H$) information

Description:$(C_2\times C_4^2).S_4$
Order: \(768\)\(\medspace = 2^{8} \cdot 3 \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $\langle(1,6,2,5)(3,8,4,7)(9,14)(10,13)(11,16)(12,15)(17,23,18,24)(19,21,20,22) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $4$

The subgroup is nonabelian and monomial (hence solvable).

Ambient group ($G$) information

Description: $(C_2\times C_4^2).\GL(2,\mathbb{Z}/4)$
Order: \(3072\)\(\medspace = 2^{10} \cdot 3 \)
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)$$C_4^2:A_4.C_2^5.C_2^3$
$\operatorname{Aut}(H)$ $C_4^2:A_4.C_4.C_2^3$
$\operatorname{res}(S)$$C_2^6:C_3\wr C_3$, of order \(5184\)\(\medspace = 2^{6} \cdot 3^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(2\)
$W$$(C_2\times C_4^2).S_4$, of order \(768\)\(\medspace = 2^{8} \cdot 3 \)
