Subgroup ($H$) information
Description: | $C_2^2:C_4^2$ |
Order: | \(64\)\(\medspace = 2^{6} \) |
Index: | \(8\)\(\medspace = 2^{3} \) |
Exponent: | \(4\)\(\medspace = 2^{2} \) |
Generators: |
$ac, b, ce$
|
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 \(176160768\)\(\medspace = 2^{23} \cdot 3 \cdot 7 \) |
$\operatorname{Aut}(H)$ | $C_2^5.D_4^2$, of order \(2048\)\(\medspace = 2^{11} \) |
$\card{W}$ | \(8\)\(\medspace = 2^{3} \) |
