Subgroup ($H$) information
Description: | $S_5$ |
Order: | \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \) |
Index: | \(15120\)\(\medspace = 2^{4} \cdot 3^{3} \cdot 5 \cdot 7 \) |
Exponent: | \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \) |
Generators: |
$\langle(2,9)(3,8,10,5,6,7), (2,9)(3,8)(5,7)(6,10)\rangle$
|
Derived length: | $1$ |
The subgroup is nonabelian, almost simple, nonsolvable, and rational.
Ambient group ($G$) information
Description: | $A_{10}$ |
Order: | \(1814400\)\(\medspace = 2^{7} \cdot 3^{4} \cdot 5^{2} \cdot 7 \) |
Exponent: | \(2520\)\(\medspace = 2^{3} \cdot 3^{2} \cdot 5 \cdot 7 \) |
Derived length: | $0$ |
The ambient group is nonabelian and simple (hence nonsolvable, perfect, quasisimple, and almost simple).
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $S_{10}$, of order \(3628800\)\(\medspace = 2^{8} \cdot 3^{4} \cdot 5^{2} \cdot 7 \) |
$\operatorname{Aut}(H)$ | $S_5$, of order \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \) |
$W$ | $S_5$, of order \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \) |
