Subgroup ($H$) information

Description:$C_{24}$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $ac, d^{2}, a^{2}d^{3}, a^{4}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $A_4:C_{24}$
Order: \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

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_2^3\times S_4$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \)
$\operatorname{Aut}(H)$ $C_2^3$, of order \(8\)\(\medspace = 2^{3} \)
$\operatorname{res}(S)$$C_2^3$, of order \(8\)\(\medspace = 2^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(4\)\(\medspace = 2^{2} \)
$W$$C_1$, of order $1$
