Subgroup ($H$) information
Description: | $C_{16}$ |
Order: | \(16\)\(\medspace = 2^{4} \) |
Index: | \(36\)\(\medspace = 2^{2} \cdot 3^{2} \) |
Exponent: | \(16\)\(\medspace = 2^{4} \) |
Generators: |
$a$
|
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: | $D_4.F_9$ |
Order: | \(576\)\(\medspace = 2^{6} \cdot 3^{2} \) |
Exponent: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Derived length: | $2$ |
The ambient group is nonabelian, monomial (hence solvable), 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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $(C_2^2\times F_9).C_2^3$ |
$\operatorname{Aut}(H)$ | $C_2\times C_4$, of order \(8\)\(\medspace = 2^{3} \) |
$\operatorname{res}(S)$ | $C_4$, of order \(4\)\(\medspace = 2^{2} \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(32\)\(\medspace = 2^{5} \) |
$W$ | $C_2$, of order \(2\) |
