Subgroup ($H$) information
Description: | $C_2\times C_{16}$ |
Order: | \(32\)\(\medspace = 2^{5} \) |
Index: | \(6\)\(\medspace = 2 \cdot 3 \) |
Exponent: | \(16\)\(\medspace = 2^{4} \) |
Generators: |
$a^{2}, b^{3}$
|
Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is normal, central (hence abelian, nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), and metacyclic.
Ambient group ($G$) information
Description: | $C_4\times C_{48}$ |
Order: | \(192\)\(\medspace = 2^{6} \cdot 3 \) |
Exponent: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The ambient group is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.
Quotient group ($Q$) structure
Description: | $C_6$ |
Order: | \(6\)\(\medspace = 2 \cdot 3 \) |
Exponent: | \(6\)\(\medspace = 2 \cdot 3 \) |
Automorphism Group: | $C_2$, of order \(2\) |
Outer Automorphisms: | $C_2$, of order \(2\) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2^6.D_4$, of order \(512\)\(\medspace = 2^{9} \) |
$\operatorname{Aut}(H)$ | $D_4:C_2^2$, of order \(32\)\(\medspace = 2^{5} \) |
$\operatorname{res}(S)$ | $D_4:C_2^2$, of order \(32\)\(\medspace = 2^{5} \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(8\)\(\medspace = 2^{3} \) |
$W$ | $C_1$, of order $1$ |
