Subgroup ($H$) information

Description:$C_3\times S_3$
Order: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Index: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a^{6}, a^{4}, cd^{2}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and an A-group.

Ambient group ($G$) information

Description: $C_3\wr C_4$
Order: \(324\)\(\medspace = 2^{2} \cdot 3^{4} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$2$

The ambient group is nonabelian, monomial (hence solvable), metabelian, and an A-group.

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\times F_9:D_6$, of order \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\operatorname{res}(S)$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(12\)\(\medspace = 2^{2} \cdot 3 \)
$W$$S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
