Subgroup ($H$) information
Description: | $C_2$ |
Order: | \(2\) |
Index: | \(860\)\(\medspace = 2^{2} \cdot 5 \cdot 43 \) |
Exponent: | \(2\) |
Generators: |
$ac^{215}$
|
Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is normal, a direct factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), central, a $p$-group, simple, and rational.
Ambient group ($G$) information
Description: | $C_2^2\times C_{430}$ |
Order: | \(1720\)\(\medspace = 2^{3} \cdot 5 \cdot 43 \) |
Exponent: | \(430\)\(\medspace = 2 \cdot 5 \cdot 43 \) |
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: | $C_2\times C_{430}$ |
Order: | \(860\)\(\medspace = 2^{2} \cdot 5 \cdot 43 \) |
Exponent: | \(430\)\(\medspace = 2 \cdot 5 \cdot 43 \) |
Automorphism Group: | $D_6\times C_{84}$, of order \(1008\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 7 \) |
Outer Automorphisms: | $D_6\times C_{84}$, of order \(1008\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 7 \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.
Automorphism information
While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2\times C_{84}\times \PSL(2,7)$ |
$\operatorname{Aut}(H)$ | $C_1$, of order $1$ |
$\operatorname{res}(S)$ | $C_1$, of order $1$ |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(4032\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 7 \) |
$W$ | $C_1$, of order $1$ |
