Subgroup ($H$) information
Description: | $C_3\times D_{43}$ |
Order: | \(258\)\(\medspace = 2 \cdot 3 \cdot 43 \) |
Index: | \(2\) |
Exponent: | \(258\)\(\medspace = 2 \cdot 3 \cdot 43 \) |
Generators: |
$a, b^{86}, b^{6}$
|
Derived length: | $2$ |
The subgroup is normal, maximal, a direct factor, nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), and hyperelementary for $p = 2$.
Ambient group ($G$) information
Description: | $C_3\times D_{86}$ |
Order: | \(516\)\(\medspace = 2^{2} \cdot 3 \cdot 43 \) |
Exponent: | \(258\)\(\medspace = 2 \cdot 3 \cdot 43 \) |
Derived length: | $2$ |
The ambient group is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, and an A-group.
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
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_{43}:(C_2^2\times C_{42})$ |
$\operatorname{Aut}(H)$ | $C_2\times F_{43}$, of order \(3612\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \cdot 43 \) |
$\operatorname{res}(S)$ | $C_2\times F_{43}$, of order \(3612\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \cdot 43 \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | $1$ |
$W$ | $D_{43}$, of order \(86\)\(\medspace = 2 \cdot 43 \) |
