Subgroup ($H$) information

Description:$C_2^2$
Order: \(4\)\(\medspace = 2^{2} \)
Index: \(453600\)\(\medspace = 2^{5} \cdot 3^{4} \cdot 5^{2} \cdot 7 \)
Exponent: \(2\)
Generators: $\langle(4,7)(5,9), (4,5)(7,9)\rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), metacyclic, 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 \(3628800\)\(\medspace = 2^{8} \cdot 3^{4} \cdot 5^{2} \cdot 7 \)
$\operatorname{Aut}(H)$ $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$W$$S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
