Subgroup ($H$) information
| Description: | $C_5\times D_{37}$ |
| Order: | \(370\)\(\medspace = 2 \cdot 5 \cdot 37 \) |
| Index: | \(2\) |
| Exponent: | \(370\)\(\medspace = 2 \cdot 5 \cdot 37 \) |
| Generators: |
$a^{2}, b^{111}, b^{5}$
|
| Derived length: | $2$ |
The subgroup is characteristic (hence normal), maximal, nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), and hyperelementary for $p = 2$.
Ambient group ($G$) information
| Description: | $C_{185}:C_4$ |
| Order: | \(740\)\(\medspace = 2^{2} \cdot 5 \cdot 37 \) |
| Exponent: | \(740\)\(\medspace = 2^{2} \cdot 5 \cdot 37 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), and hyperelementary for $p = 2$.
Quotient group ($Q$) structure
| Description: | $C_2$ |
| Order: | \(2\) |
| Exponent: | \(2\) |
| Automorphism Group: | $C_1$, of order $1$ |
| Outer Automorphisms: | $C_1$, of order $1$ |
| Derived length: | $1$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, and rational.
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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{185}.C_9.C_4^2$ |
| $\operatorname{Aut}(H)$ | $C_4\times F_{37}$, of order \(5328\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 37 \) |
| $\operatorname{res}(\operatorname{Aut}(G))$ | $C_4\times F_{37}$, of order \(5328\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 37 \) |
| $\card{\operatorname{ker}(\operatorname{res})}$ | \(5\) |
| $W$ | $C_{37}:C_4$, of order \(148\)\(\medspace = 2^{2} \cdot 37 \) |
