Subgroup ($H$) information
Description: | $C_2\times C_7^3:S_4$ |
Order: | \(16464\)\(\medspace = 2^{4} \cdot 3 \cdot 7^{3} \) |
Index: | \(56\)\(\medspace = 2^{3} \cdot 7 \) |
Exponent: | \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \) |
Generators: |
$\langle(8,10,12,14,9,11,13)(15,17,19,21,16,18,20)(22,25,28,24,27,23,26), (22,28,27,26,25,24,23) \!\cdots\! \rangle$
|
Derived length: | $4$ |
The subgroup is nonabelian and monomial (hence solvable).
Ambient group ($G$) information
Description: | $D_7\wr S_4$ |
Order: | \(921984\)\(\medspace = 2^{7} \cdot 3 \cdot 7^{4} \) |
Exponent: | \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \) |
Derived length: | $5$ |
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_7^4.C_2^3.(C_6\times S_4)$, of order \(2765952\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 7^{4} \) |
$\operatorname{Aut}(H)$ | $D_7^3:(C_6\times S_3)$, of order \(98784\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 7^{3} \) |
$W$ | $D_7\wr S_3$, of order \(16464\)\(\medspace = 2^{4} \cdot 3 \cdot 7^{3} \) |
