Subgroup ($H$) information
| Description: | $C_2^2\times C_{344}$ |
| Order: | \(1376\)\(\medspace = 2^{5} \cdot 43 \) |
| Index: | $1$ |
| Exponent: | \(344\)\(\medspace = 2^{3} \cdot 43 \) |
| Generators: |
$c^{8}, c^{86}, c^{172}, c^{43}, b, a$
|
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is the center (hence characteristic, normal, abelian, central, nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), the Fitting subgroup, the radical, a direct factor, a Hall subgroup, and elementary for $p = 2$ (hence hyperelementary).
Ambient group ($G$) information
| Description: | $C_2^2\times C_{344}$ |
| Order: | \(1376\)\(\medspace = 2^{5} \cdot 43 \) |
| Exponent: | \(344\)\(\medspace = 2^{3} \cdot 43 \) |
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The ambient group is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group) and elementary for $p = 2$ (hence hyperelementary).
Quotient group ($Q$) structure
| Description: | $C_1$ |
| Order: | $1$ |
| Exponent: | $1$ |
| Automorphism Group: | $C_1$, of order $1$ |
| Outer Automorphisms: | $C_1$, of order $1$ |
| Nilpotency class: | $0$ |
| 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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_2^3:A_4.C_{42}.C_2^2$ |
| $\operatorname{Aut}(H)$ | $C_2^3:A_4.C_{42}.C_2^2$ |
| $W$ | $C_1$, of order $1$ |
