Subgroup ($H$) information

Description:$C_6:S_4$
Order: \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Index: \(56\)\(\medspace = 2^{3} \cdot 7 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(4,7)(5,6), (1,3,2)(8,14)(9,15)(10,11)(12,13), (1,2,3)(8,15,9)(10,13,11) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

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

Ambient group ($G$) information

Description: $C_3:D_4\times \PGL(2,7)$
Order: \(8064\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 7 \)
Exponent: \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
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)$$C_2^2\times \SO(3,7)\times D_6$, of order \(16128\)\(\medspace = 2^{8} \cdot 3^{2} \cdot 7 \)
$\operatorname{Aut}(H)$ $C_2\times C_6^2:D_6$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$W$$D_6\times S_4$, of order \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
