Subgroup ($H$) information
Description: | $\OD_{16}:C_2$ |
Order: | \(32\)\(\medspace = 2^{5} \) |
Index: | \(6\)\(\medspace = 2 \cdot 3 \) |
Exponent: | \(8\)\(\medspace = 2^{3} \) |
Generators: |
$a, b^{2}, c^{9}$
|
Nilpotency class: | $2$ |
Derived length: | $2$ |
The subgroup is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metabelian.
Ambient group ($G$) information
Description: | $C_8.D_{12}$ |
Order: | \(192\)\(\medspace = 2^{6} \cdot 3 \) |
Exponent: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Derived length: | $2$ |
The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, 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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_4\times D_4\times D_6$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \) |
$\operatorname{Aut}(H)$ | $C_2^2\times S_4$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \) |
$\operatorname{res}(S)$ | $C_2^2\times D_4$, of order \(32\)\(\medspace = 2^{5} \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(4\)\(\medspace = 2^{2} \) |
$W$ | $D_4$, of order \(8\)\(\medspace = 2^{3} \) |
