Subgroup ($H$) information
Description: | $C_8$ |
Order: | \(8\)\(\medspace = 2^{3} \) |
Index: | \(3\) |
Exponent: | \(8\)\(\medspace = 2^{3} \) |
Generators: |
$a^{3}$
|
Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is characteristic (hence normal), maximal, a direct factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), central, a $2$-Sylow subgroup (hence a Hall subgroup), and a $p$-group.
Ambient group ($G$) information
Description: | $C_{24}$ |
Order: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
Exponent: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The ambient group is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).
Quotient group ($Q$) structure
Description: | $C_3$ |
Order: | \(3\) |
Exponent: | \(3\) |
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, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, and simple.
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 $W = G / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2^3$, of order \(8\)\(\medspace = 2^{3} \) |
$\operatorname{Aut}(H)$ | $C_2^2$, of order \(4\)\(\medspace = 2^{2} \) |
$\operatorname{res}(\operatorname{Aut}(G))$ | $C_2^2$, of order \(4\)\(\medspace = 2^{2} \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(2\) |
$W$ | $C_1$, of order $1$ |
