Subgroup ($H$) information

Description:$C_6^2$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Index: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $c^{3}, d^{3}, c^{2}, d^{2}$ 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) and metacyclic.

Ambient group ($G$) information

Description: $(C_3\times \He_3):S_4$
Order: \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
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{res}(S)$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
$W$$C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \)
