Subgroup ($H$) information

Description:$C_7^2:C_{14}$
Order: \(686\)\(\medspace = 2 \cdot 7^{3} \)
Index: \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Exponent: \(14\)\(\medspace = 2 \cdot 7 \)
Generators: $c^{7}d^{4}, d^{2}, e, c^{2}f$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $D_7\times C_7^3:S_4$
Order: \(115248\)\(\medspace = 2^{4} \cdot 3 \cdot 7^{4} \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$4$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

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)$$C_7^3.(C_7\times A_4).C_6^2.C_2$
$\operatorname{Aut}(H)$ $C_6\times C_7^2:C_3.\SL(2,7).C_2$
$W$$D_7\wr C_2$, of order \(392\)\(\medspace = 2^{3} \cdot 7^{2} \)
