Subgroup ($H$) information

Description:$C_5\times D_{10}$
Order: \(100\)\(\medspace = 2^{2} \cdot 5^{2} \)
Index: \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $\langle(2,4)(3,5), (6,7,10,8,9), (1,13,11,14,12)(2,4)(3,5)(7,9)(8,10), (6,7)(9,10)\rangle$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and an A-group.

Ambient group ($G$) information

Description: $A_4\times F_5\times S_5$
Order: \(28800\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 5^{2} \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

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)$$F_5\times S_4\times S_5$, of order \(57600\)\(\medspace = 2^{8} \cdot 3^{2} \cdot 5^{2} \)
$\operatorname{Aut}(H)$ $C_{10}:C_4^2$, of order \(160\)\(\medspace = 2^{5} \cdot 5 \)
$W$$C_4\times F_5$, of order \(80\)\(\medspace = 2^{4} \cdot 5 \)
