Subgroup ($H$) information

Description:$D_5^2$
Order: \(100\)\(\medspace = 2^{2} \cdot 5^{2} \)
Index: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $\langle(1,3,2,5,4)(11,14)(13,15), (1,4,5,2,3), (11,15,12,13,14), (1,2)(4,5)\rangle$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $A_5\times C_5:F_5$
Order: \(6000\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{3} \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, an A-group, 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)$$S_5\times F_5^2$, of order \(48000\)\(\medspace = 2^{7} \cdot 3 \cdot 5^{3} \)
$\operatorname{Aut}(H)$ $F_5\wr C_2$, of order \(800\)\(\medspace = 2^{5} \cdot 5^{2} \)
$W$$D_5\times F_5$, of order \(200\)\(\medspace = 2^{3} \cdot 5^{2} \)
