Subgroup ($H$) information
| Description: | $C_{18}$ |
| Order: | \(18\)\(\medspace = 2 \cdot 3^{2} \) |
| Index: | \(3440\)\(\medspace = 2^{4} \cdot 5 \cdot 43 \) |
| Exponent: | \(18\)\(\medspace = 2 \cdot 3^{2} \) |
| Generators: |
$b^{15480}, b^{6880}, b^{20640}$
|
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is characteristic (hence normal) and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group). Whether it is a direct factor or a semidirect factor has not been computed.
Ambient group ($G$) information
| Description: | $C_{1935}:Q_{32}$ |
| Order: | \(61920\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 5 \cdot 43 \) |
| Exponent: | \(30960\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5 \cdot 43 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and hyperelementary for $p = 2$.
Quotient group ($Q$) structure
| Description: | $D_8\times C_{215}$ |
| Order: | \(3440\)\(\medspace = 2^{4} \cdot 5 \cdot 43 \) |
| Exponent: | \(1720\)\(\medspace = 2^{3} \cdot 5 \cdot 43 \) |
| Automorphism Group: | $C_2\times C_{84}\times C_8:C_2^2$ |
| Outer Automorphisms: | $C_2^3\times C_{84}$, of order \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \) |
| Nilpotency class: | $3$ |
| Derived length: | $2$ |
The quotient is nonabelian, elementary for $p = 2$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), and metacyclic (hence metabelian).
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 \(1161216\)\(\medspace = 2^{11} \cdot 3^{4} \cdot 7 \) |
| $\operatorname{Aut}(H)$ | $C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
| $\card{W}$ | not computed |
