Subgroup ($H$) information

Description:$C_9^2:C_6$
Order: \(486\)\(\medspace = 2 \cdot 3^{5} \)
Index: \(3\)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Generators: $a^{3}, d^{3}, c^{3}, a^{2}, bd^{5}, cd^{3}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $(C_3\times C_9^2):C_6$
Order: \(1458\)\(\medspace = 2 \cdot 3^{6} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

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_3^4\times C_9).C_3^4.C_2^3$, of order \(472392\)\(\medspace = 2^{3} \cdot 3^{10} \)
$\operatorname{Aut}(H)$ $C_9^2:C_3^2:D_6$, of order \(8748\)\(\medspace = 2^{2} \cdot 3^{7} \)
$\operatorname{res}(S)$$C_9^2:C_3^2:D_6$, of order \(8748\)\(\medspace = 2^{2} \cdot 3^{7} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(6\)\(\medspace = 2 \cdot 3 \)
$W$$C_9^2:C_6$, of order \(486\)\(\medspace = 2 \cdot 3^{5} \)
