Subgroup ($H$) information
| Description: | $C_{344}$ |
| Order: | \(344\)\(\medspace = 2^{3} \cdot 43 \) |
| Index: | \(15\)\(\medspace = 3 \cdot 5 \) |
| Exponent: | \(344\)\(\medspace = 2^{3} \cdot 43 \) |
| Generators: |
$a^{645}, a^{120}, a^{2580}, a^{1290}$
|
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is characteristic (hence normal), a direct factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,43$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), central, and a Hall subgroup.
Ambient group ($G$) information
| Description: | $C_{5160}$ |
| Order: | \(5160\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 43 \) |
| Exponent: | \(5160\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 43 \) |
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The ambient group is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3,5,43$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).
Quotient group ($Q$) structure
| Description: | $C_{15}$ |
| Order: | \(15\)\(\medspace = 3 \cdot 5 \) |

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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_2^4\times C_{84}$, of order \(1344\)\(\medspace = 2^{6} \cdot 3 \cdot 7 \) |
| $\operatorname{Aut}(H)$ | $C_2^2\times C_{42}$, of order \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \) |
| $W$ | $C_1$, of order $1$ |
