Subgroup ($H$) information

Description:$S_3\times A_4$
Order: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(10,13)(11,12), (2,8,5)(4,9,7)(11,13,12), (2,7)(3,6)(4,8)(5,9), (10,12)(11,13), (1,6,3)(2,8,5)(4,7,9)\rangle$ 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: $C_6^2:\GL(2,3)$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
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_2^2:S_4:C_2$, of order \(3456\)\(\medspace = 2^{7} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $S_3\times S_4$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
$\operatorname{res}(S)$$S_3\times S_4$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(2\)
$W$$S_3\times S_4$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
