Subgroup ($H$) information

Description:$C_6:C_{16}$
Order: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Index: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Generators: $b, e^{4}, e^{6}, e^{3}, b^{2}, b^{4}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, and an A-group.

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 \(6912\)\(\medspace = 2^{8} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $D_{12}:C_2^3$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \)
$\operatorname{res}(S)$$C_4\times D_6$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(16\)\(\medspace = 2^{4} \)
$W$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
