Subgroup ($H$) information

Description:$C_2\times S_4$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Index: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(10,13)(11,12), (5,8,7), (5,6)(7,8), (7,8)(11,12), (5,7)(6,8)\rangle$ Copy content Toggle raw display
Derived length: $3$

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

Ambient group ($G$) information

Description: $A_4^2:\SOPlus(4,2)$
Order: \(10368\)\(\medspace = 2^{7} \cdot 3^{4} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence 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)$$S_4^2.\SOPlus(4,2)$, of order \(41472\)\(\medspace = 2^{9} \cdot 3^{4} \)
$\operatorname{Aut}(H)$ $C_2\times S_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$W$$C_2\times S_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
