Subgroup ($H$) information

Description:$C_3:S_3$
Order: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Index: \(448\)\(\medspace = 2^{6} \cdot 7 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(8,10,12)(9,13,15), (1,2)(4,7)(8,12)(11,14)(13,15), (1,3,2)\rangle$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, supersolvable (hence solvable and monomial), metabelian, an A-group, 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 \(16128\)\(\medspace = 2^{8} \cdot 3^{2} \cdot 7 \)
$\operatorname{Aut}(H)$ $C_3^2:\GL(2,3)$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
$W$$S_3^2$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
