Subgroup ($H$) information
| Description: | $C_{23}$ |
| Order: | \(23\) |
| Index: | \(50\)\(\medspace = 2 \cdot 5^{2} \) |
| Exponent: | \(23\) |
| Generators: |
$a^{50}$

| 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 $23$-Sylow subgroup (hence a Hall subgroup), a $p$-group, and simple.
Ambient group ($G$) information
| Description: | $C_{1150}$ |
| Order: | \(1150\)\(\medspace = 2 \cdot 5^{2} \cdot 23 \) |
| Exponent: | \(1150\)\(\medspace = 2 \cdot 5^{2} \cdot 23 \) |
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The ambient group is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,5,23$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,5$), 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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_2\times C_{220}$, of order \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \) |
| $\operatorname{Aut}(H)$ | $C_{22}$, of order \(22\)\(\medspace = 2 \cdot 11 \) |
| $\operatorname{res}(\operatorname{Aut}(G))$ | $C_{22}$, of order \(22\)\(\medspace = 2 \cdot 11 \) |
| $\card{\operatorname{ker}(\operatorname{res})}$ | \(20\)\(\medspace = 2^{2} \cdot 5 \) |
| $W$ | $C_1$, of order $1$ |
