Subgroup ($H$) information
Description: | $C_{17}$ |
Order: | \(17\) |
Index: | \(28\)\(\medspace = 2^{2} \cdot 7 \) |
Exponent: | \(17\) |

$a^{28}$

Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is characteristic (hence normal), a direct factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), central, a $17$-Sylow subgroup (hence a Hall subgroup), a $p$-group, and simple.
Ambient group ($G$) information
Description: | $C_{476}$ |
Order: | \(476\)\(\medspace = 2^{2} \cdot 7 \cdot 17 \) |
Exponent: | \(476\)\(\medspace = 2^{2} \cdot 7 \cdot 17 \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The ambient group is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,7,17$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).
Quotient group ($Q$) structure

Nilpotency class: | $1$ |
Derived length: | $1$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,7$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).
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 $W = G / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2^2\times C_{48}$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \) |
$\operatorname{Aut}(H)$ | $C_{16}$, of order \(16\)\(\medspace = 2^{4} \) |
$\operatorname{res}(\operatorname{Aut}(G))$ | $C_{16}$, of order \(16\)\(\medspace = 2^{4} \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
$W$ | $C_1$, of order $1$ |
