Subgroup ($H$) information

Description:$C_6\times S_3$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Index: \(80\)\(\medspace = 2^{4} \cdot 5 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(3,4,5), (6,7)(8,9)(12,13), (1,2)(3,5)(6,7)(8,9)(12,13), (6,8,13)(7,9,12)\rangle$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and an A-group.

Ambient group ($G$) information

Description: $C_2^4:\GL(2,4)$
Order: \(2880\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5 \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, an A-group, 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_3\times S_4\times S_5$, of order \(17280\)\(\medspace = 2^{7} \cdot 3^{3} \cdot 5 \)
$\operatorname{Aut}(H)$ $C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\operatorname{res}(S)$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(12\)\(\medspace = 2^{2} \cdot 3 \)
$W$$S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
