Subgroup ($H$) information

Description:$C_8$
Order: \(8\)\(\medspace = 2^{3} \)
Index: \(3\)
Exponent: \(8\)\(\medspace = 2^{3} \)
Generators: $a^{3}$ Copy content Toggle raw display
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 $1$
