Subgroup ($H$) information

Description:$C_3^2:C_{12}$
Order: \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
Index: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(1,10,6,2)(3,7,4,9)(11,12,13), (1,6,5)(2,4,7)(3,10,9)(11,13,12), (1,9,4)(2,5,10)(3,7,6)(11,12,13), (11,13,12), (1,6)(2,10)(3,4)(7,9)\rangle$ 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: $A_6:S_3$
Order: \(2160\)\(\medspace = 2^{4} \cdot 3^{3} \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian and nonsolvable.

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_6:D_6$, of order \(8640\)\(\medspace = 2^{6} \cdot 3^{3} \cdot 5 \)
$\operatorname{Aut}(H)$ $F_9:C_2^2$, of order \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
$\operatorname{res}(S)$$F_9:C_2^2$, of order \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(3\)
$W$$F_9$, of order \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
