Subgroup ($H$) information

Description:$C_3^2$
Order: \(9\)\(\medspace = 3^{2} \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(3\)
Generators: $c^{4}, e$ 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: $C_6.\SOPlus(4,2)$
Order: \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
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_2^2\times \He_3:D_4$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $\GL(2,3)$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\operatorname{res}(S)$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
$W$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
