Subgroup ($H$) information

Description:$C_2\times C_8$
Order: \(16\)\(\medspace = 2^{4} \)
Index: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Generators: $a, c^{3}d^{3}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $(C_3^2\times A_4):C_8$
Order: \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
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_2^2\times C_3^4.(Q_8\times A_4).D_6$
$\operatorname{Aut}(H)$ $C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \)
$\operatorname{res}(S)$$C_2^3$, of order \(8\)\(\medspace = 2^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
$W$$C_2$, of order \(2\)
