Subgroup ($H$) information
Description: | $S_4$ |
Order: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
Index: | \(1372\)\(\medspace = 2^{2} \cdot 7^{3} \) |
Exponent: | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
Generators: |
$ae^{10}f^{8}, bcd^{10}e^{12}f^{8}, cd^{3}e^{10}f^{6}, d^{7}e^{10}$
|
Derived length: | $3$ |
The subgroup is nonabelian, monomial (hence solvable), and rational.
Ambient group ($G$) information
Description: | $(C_7\times C_{14}^2):S_4$ |
Order: | \(32928\)\(\medspace = 2^{5} \cdot 3 \cdot 7^{3} \) |
Exponent: | \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \) |
Derived length: | $4$ |
The ambient group is nonabelian and monomial (hence 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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_7^3.C_2^4.C_6^2.C_2$ |
$\operatorname{Aut}(H)$ | $S_4$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \) |
$W$ | $S_4$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \) |
