Subgroup ($H$) information

Description:$D_6\times A_5$
Order: \(720\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5 \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Generators: $\langle(9,10), (2,4,3)(6,7)(11,12), (6,7,8)(11,13,12), (6,8)(12,13), (1,2)(3,5)(6,8)(9,10)(12,13)\rangle$ Copy content Toggle raw display

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

Ambient group ($G$) information

Description: $A_5:D_6^2$
Order: \(8640\)\(\medspace = 2^{6} \cdot 3^{3} \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, nonsolvable, and rational.

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)$$D_6\wr C_2.C_2.S_5$
$\operatorname{Aut}(H)$ $D_6\times S_5$, of order \(1440\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 5 \)
$W$$S_3\times S_5$, of order \(720\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5 \)
