Subgroup ($H$) information
| Description: | $C_2$ |
| Order: | \(2\) |
| Index: | \(4080\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \cdot 17 \) |
| Exponent: | \(2\) |
| Generators: |
$\langle(1,17)(2,3)(5,9)(7,8)(10,15)(11,12)\rangle$
|
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, and rational.
Ambient group ($G$) information
| Description: | $\SOMinus(4,4)$ |
| Order: | \(8160\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \cdot 17 \) |
| Exponent: | \(1020\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \cdot 17 \) |
| Derived length: | $1$ |
The ambient group is nonabelian, almost simple, and nonsolvable.
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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $\SL(2,16).C_4$, of order \(16320\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \cdot 17 \) |
| $\operatorname{Aut}(H)$ | $C_1$, of order $1$ |
| $W$ | $C_1$, of order $1$ |
