Subgroup ($H$) information

Description:$D_5^2$
Order: \(100\)\(\medspace = 2^{2} \cdot 5^{2} \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $\langle(7,9)(8,10)(12,14), (6,7,8,10,9), (1,4)(2,5)(6,7)(8,9)(11,13), (1,4,5,3,2)\rangle$ 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: $C_5:D_4\times A_5$
Order: \(2400\)\(\medspace = 2^{5} \cdot 3 \cdot 5^{2} \)
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)$$C_2^2\times F_5\times S_5$, of order \(9600\)\(\medspace = 2^{7} \cdot 3 \cdot 5^{2} \)
$\operatorname{Aut}(H)$ $F_5\wr C_2$, of order \(800\)\(\medspace = 2^{5} \cdot 5^{2} \)
$\operatorname{res}(S)$$F_5^2$, of order \(400\)\(\medspace = 2^{4} \cdot 5^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(2\)
$W$$D_5^2$, of order \(100\)\(\medspace = 2^{2} \cdot 5^{2} \)
