Subgroup ($H$) information
| Description: | $C_5^7.S_7$ |
| Order: | \(393750000\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5^{8} \cdot 7 \) |
| Index: | \(2\) |
| Exponent: | \(2100\)\(\medspace = 2^{2} \cdot 3 \cdot 5^{2} \cdot 7 \) |
| Generators: |
$\langle(1,2,3,4,5)(6,7,8,9,10)(11,12,13,14,15)(16,17,18,19,20)(21,22,23,24,25) \!\cdots\! \rangle$
|
| Derived length: | $2$ |
The subgroup is characteristic (hence normal), maximal, nonabelian, and nonsolvable. Whether it is a direct factor or a semidirect factor has not been computed.
Ambient group ($G$) information
| Description: | $C_5^6.(D_5\times S_7)$ |
| Order: | \(787500000\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 5^{8} \cdot 7 \) |
| Exponent: | \(2100\)\(\medspace = 2^{2} \cdot 3 \cdot 5^{2} \cdot 7 \) |
| Derived length: | $2$ |
The ambient group is nonabelian and nonsolvable.
Quotient group ($Q$) structure
| Description: | $C_2$ |
| Order: | \(2\) |
| Exponent: | \(2\) |
| Automorphism Group: | $C_1$, of order $1$ |
| Outer Automorphisms: | $C_1$, of order $1$ |
| Derived length: | $1$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, and rational.
Automorphism information
Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | Group of order \(6300000000\)\(\medspace = 2^{8} \cdot 3^{2} \cdot 5^{8} \cdot 7 \) |
| $\operatorname{Aut}(H)$ | Group of order \(6300000000\)\(\medspace = 2^{8} \cdot 3^{2} \cdot 5^{8} \cdot 7 \) |
| $\card{W}$ | not computed |
