Nilpotency class: | $2$ |
Derived length: | $2$ |
The subgroup is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metacyclic (hence metabelian).
Ambient group ($G$) information
Description: | $D_{24}.C_{96}$ |
Order: | \(4608\)\(\medspace = 2^{9} \cdot 3^{2} \) |
Exponent: | \(192\)\(\medspace = 2^{6} \cdot 3 \) |
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_3:((C_4\times C_8).C_2^6.C_2)$ |
$\operatorname{Aut}(H)$ | $D_4:C_2^2$, of order \(32\)\(\medspace = 2^{5} \) |
$\operatorname{res}(S)$ | $D_4:C_2^2$, of order \(32\)\(\medspace = 2^{5} \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(64\)\(\medspace = 2^{6} \) |
$W$ | $D_4$, of order \(8\)\(\medspace = 2^{3} \) |
