Order: \(900\)\(\medspace = 2^{2} \cdot 3^{2} \cdot 5^{2} \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Generators: $\langle(1,3,5)(4,8,10,6,9)(11,13,12), (2,3)(4,8,10,6,9)(5,7), (11,12,13), (4,8,10,6,9)(11,13,12)\rangle$ Copy content Toggle raw display
Derived length: $1$

The subgroup is nonabelian, an A-group, and nonsolvable.

Ambient group ($G$) information

Description: $A_5^2:C_6$
Order: \(21600\)\(\medspace = 2^{5} \cdot 3^{3} \cdot 5^{2} \)

Derived length:$1$

The ambient group is nonabelian 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)$$A_5^2:C_2^3$, of order \(28800\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 5^{2} \)
$\operatorname{Aut}(H)$ $C_2\times C_4\times S_5$, of order \(960\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \)
$W$$C_2\times A_5$, of order \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
