Subgroup ($H$) information
Description: | $C_3\times C_6$ |
Order: | \(18\)\(\medspace = 2 \cdot 3^{2} \) |
Index: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
Exponent: | \(6\)\(\medspace = 2 \cdot 3 \) |
Generators: |
$d^{6}, b, c^{2}d^{6}$
|
Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 3$ (hence hyperelementary), and metacyclic.
Ambient group ($G$) information
Description: | $C_3^2:\GL(2,3)$ |
Order: | \(432\)\(\medspace = 2^{4} \cdot 3^{3} \) |
Exponent: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2\times C_6^2:D_6$, 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 \(12\)\(\medspace = 2^{2} \cdot 3 \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(6\)\(\medspace = 2 \cdot 3 \) |
$W$ | $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
