Subgroup ($H$) information
| Description: | $D_{10}\times S_4$ |
| Order: | \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \) |
| Index: | \(20\)\(\medspace = 2^{2} \cdot 5 \) |
| Exponent: | \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \) |
| Generators: |
$\langle(6,9)(7,8)(12,13,14), (6,8,7,9,10), (2,3)(4,5), (7,9)(8,10)(11,12)(13,14) \!\cdots\! \rangle$
|
| Derived length: | $3$ |
The subgroup is nonabelian and monomial (hence solvable).
Ambient group ($G$) information
| Description: | $C_4\times F_5\times S_5$ |
| Order: | \(9600\)\(\medspace = 2^{7} \cdot 3 \cdot 5^{2} \) |
| Exponent: | \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \) |
| 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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $(C_2\times D_4\times F_5).S_5$, of order \(38400\)\(\medspace = 2^{9} \cdot 3 \cdot 5^{2} \) |
| $\operatorname{Aut}(H)$ | $C_2^2\times F_5\times S_4$, of order \(1920\)\(\medspace = 2^{7} \cdot 3 \cdot 5 \) |
| $W$ | $F_5\times S_4$, of order \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \) |
