Subgroup ($H$) information
Description: | $C_4$ |
Order: | \(4\)\(\medspace = 2^{2} \) |
Index: | \(162\)\(\medspace = 2 \cdot 3^{4} \) |
Exponent: | \(4\)\(\medspace = 2^{2} \) |
Generators: |
$ab$
|
Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group) and a $p$-group.
Ambient group ($G$) information
Description: | $S_3\times \He_3:C_4$ |
Order: | \(648\)\(\medspace = 2^{3} \cdot 3^{4} \) |
Exponent: | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
Derived length: | $3$ |
The ambient group is nonabelian and supersolvable (hence solvable and monomial).
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $\GL(2,3).C_2^6$, of order \(10368\)\(\medspace = 2^{7} \cdot 3^{4} \) |
$\operatorname{Aut}(H)$ | $C_2$, of order \(2\) |
$\operatorname{res}(S)$ | $C_2$, of order \(2\) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(192\)\(\medspace = 2^{6} \cdot 3 \) |
$W$ | $C_1$, of order $1$ |
