Subgroup ($H$) information
| Description: | $C_9^2:(C_3\times C_6)$ |
| Order: | \(1458\)\(\medspace = 2 \cdot 3^{6} \) |
| Index: | \(3\) |
| Exponent: | \(18\)\(\medspace = 2 \cdot 3^{2} \) |
| Generators: |
$a^{3}, c^{3}e^{6}, c^{3}de^{7}, a^{2}, e^{3}, b, cd^{2}e^{8}$
|
| Derived length: | $2$ |
The subgroup is maximal, nonabelian, supersolvable (hence solvable and monomial), and metabelian.
Ambient group ($G$) information
| Description: | $C_9^2.(S_3\times C_3^2)$ |
| Order: | \(4374\)\(\medspace = 2 \cdot 3^{7} \) |
| 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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_3^3.C_3^3.C_3^3.C_6.C_2$, of order \(236196\)\(\medspace = 2^{2} \cdot 3^{10} \) |
| $\operatorname{Aut}(H)$ | $C_9^2:C_3^2:D_6$, of order \(8748\)\(\medspace = 2^{2} \cdot 3^{7} \) |
| $\operatorname{res}(S)$ | $C_9^2:C_3^2:D_6$, of order \(8748\)\(\medspace = 2^{2} \cdot 3^{7} \) |
| $\card{\operatorname{ker}(\operatorname{res})}$ | \(3\) |
| $W$ | $C_9^2:(C_3\times C_6)$, of order \(1458\)\(\medspace = 2 \cdot 3^{6} \) |
