Subgroup ($H$) information
| Description: | $C_{10}$ |
| Order: | \(10\)\(\medspace = 2 \cdot 5 \) |
| Index: | \(92\)\(\medspace = 2^{2} \cdot 23 \) |
| Exponent: | \(10\)\(\medspace = 2 \cdot 5 \) |
| Generators: |
$a^{2}, c^{46}$
|
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is characteristic (hence normal) and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,5$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).
Ambient group ($G$) information
| Description: | $D_{115}:C_4$ |
| Order: | \(920\)\(\medspace = 2^{3} \cdot 5 \cdot 23 \) |
| Exponent: | \(460\)\(\medspace = 2^{2} \cdot 5 \cdot 23 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, metabelian, and an A-group.
Quotient group ($Q$) structure
| Description: | $D_{46}$ |
| Order: | \(92\)\(\medspace = 2^{2} \cdot 23 \) |
| Exponent: | \(46\)\(\medspace = 2 \cdot 23 \) |
| Automorphism Group: | $C_2\times F_{23}$, of order \(1012\)\(\medspace = 2^{2} \cdot 11 \cdot 23 \) |
| Outer Automorphisms: | $C_{22}$, of order \(22\)\(\medspace = 2 \cdot 11 \) |
| Nilpotency class: | $-1$ |
| Derived length: | $2$ |
The quotient is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, 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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{115}.C_{44}.C_2^3$, of order \(40480\)\(\medspace = 2^{5} \cdot 5 \cdot 11 \cdot 23 \) |
| $\operatorname{Aut}(H)$ | $C_4$, of order \(4\)\(\medspace = 2^{2} \) |
| $\operatorname{res}(\operatorname{Aut}(G))$ | $C_4$, of order \(4\)\(\medspace = 2^{2} \) |
| $\card{\operatorname{ker}(\operatorname{res})}$ | \(10120\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \cdot 23 \) |
| $W$ | $C_2$, of order \(2\) |
