Subgroup ($H$) information
| Description: | $C_5^4:(C_4^2:C_2)$ |
| Order: | \(20000\)\(\medspace = 2^{5} \cdot 5^{4} \) |
| Index: | \(2\) |
| Exponent: | \(20\)\(\medspace = 2^{2} \cdot 5 \) |
| Generators: |
$g^{2}, f, bd^{7}f^{3}g^{4}, d^{2}fg^{4}, c^{2}d^{6}e^{2}f^{4}, ef^{2}g^{8}, aef^{4}, cd^{5}, g^{5}$
|
| Derived length: | $3$ |
The subgroup is characteristic (hence normal), maximal, a semidirect factor, nonabelian, and solvable. Whether it is monomial has not been computed.
Ambient group ($G$) information
| Description: | $(\SO(3,7)\times S_4^2).C_2^2$ |
| Order: | \(40000\)\(\medspace = 2^{6} \cdot 5^{4} \) |
| Exponent: | \(20\)\(\medspace = 2^{2} \cdot 5 \) |
| Derived length: | $3$ |
The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.
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 \(1280000\)\(\medspace = 2^{11} \cdot 5^{4} \) |
| $\operatorname{Aut}(H)$ | $C_5^4.C_4.C_2^5.C_2^4$ |
| $W$ | $C_5:D_5^3:C_2^2$, of order \(20000\)\(\medspace = 2^{5} \cdot 5^{4} \) |
