Subgroup ($H$) information
| Description: | $C_5\times D_{148}$ |
| Order: | \(1480\)\(\medspace = 2^{3} \cdot 5 \cdot 37 \) |
| Index: | $1$ |
| Exponent: | \(740\)\(\medspace = 2^{2} \cdot 5 \cdot 37 \) |
| Generators: |
$b^{370}, b^{20}, b^{444}, b^{185}, a$
|
| Derived length: | $2$ |
The subgroup is the radical (hence characteristic, normal, and solvable), a direct factor, nonabelian, a Hall subgroup, metacyclic (hence supersolvable, monomial, and metabelian), and hyperelementary for $p = 2$.
Ambient group ($G$) information
| Description: | $C_5\times D_{148}$ |
| Order: | \(1480\)\(\medspace = 2^{3} \cdot 5 \cdot 37 \) |
| Exponent: | \(740\)\(\medspace = 2^{2} \cdot 5 \cdot 37 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and hyperelementary for $p = 2$.
Quotient group ($Q$) structure
| Description: | $C_1$ |
| Order: | $1$ |
| Exponent: | $1$ |
| Automorphism Group: | $C_1$, of order $1$ |
| Outer Automorphisms: | $C_1$, of order $1$ |
| Derived length: | $0$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary (for every $p$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group (for every $p$), perfect, 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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{74}.C_{18}.C_2.C_2^4$ |
| $\operatorname{Aut}(H)$ | $C_{74}.C_{18}.C_2.C_2^4$ |
| $W$ | $D_{74}$, of order \(148\)\(\medspace = 2^{2} \cdot 37 \) |
