| Nilpotency class: | $7$ |
| 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: | $C_{32}.D_{128}$ |
| Order: | \(8192\)\(\medspace = 2^{13} \) |
| Exponent: | \(256\)\(\medspace = 2^{8} \) |
| Nilpotency class: | $8$ |
| Derived length: | $2$ |
The ambient group is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), 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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{64}.C_8.C_4^2.C_2^5$ |
| $\operatorname{Aut}(H)$ | $C_{32}.C_{32}.C_2^4$ |
| $W$ | $D_{64}$, of order \(128\)\(\medspace = 2^{7} \) |
