Subgroup ($H$) information

Description:$C_3\times D_{12}$
Order: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $a, e^{4}, e^{3}, d, e^{6}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian and metacyclic (hence solvable, supersolvable, monomial, and metabelian).

Ambient group ($G$) information

Description: $(C_4\times \He_3).\SD_{16}$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Derived length:$4$

The ambient group is nonabelian and 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_3^2:S_3.C_2^4.C_2^3$, of order \(6912\)\(\medspace = 2^{8} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $D_4\times D_6$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$\operatorname{res}(S)$$C_2\times D_{12}$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(12\)\(\medspace = 2^{2} \cdot 3 \)
$W$$C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
