Subgroup ($H$) information
| Description: | $C_2^3.D_4$ |
| Order: | \(64\)\(\medspace = 2^{6} \) |
| Index: | \(8\)\(\medspace = 2^{3} \) |
| Exponent: | \(4\)\(\medspace = 2^{2} \) |
| Generators: |
$a, b, ce$
|
| 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: | $C_2^4.C_2^5$ |
| Order: | \(512\)\(\medspace = 2^{9} \) |
| Exponent: | \(4\)\(\medspace = 2^{2} \) |
| Nilpotency class: | $2$ |
| 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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_2^{16}.\PSL(2,7)$, of order \(176160768\)\(\medspace = 2^{23} \cdot 3 \cdot 7 \) |
| $\operatorname{Aut}(H)$ | $C_2^9.C_2$, of order \(1024\)\(\medspace = 2^{10} \) |
| $\card{W}$ | \(8\)\(\medspace = 2^{3} \) |
