Subgroup ($H$) information
| Description: | $C_2\times D_4$ |
| Order: | \(16\)\(\medspace = 2^{4} \) |
| Index: | \(3000\)\(\medspace = 2^{3} \cdot 3 \cdot 5^{3} \) |
| Exponent: | \(4\)\(\medspace = 2^{2} \) |
| Generators: |
$\langle(3,5)(6,7)(8,9)(11,13)(12,15), (6,7)(8,9)(11,13)(12,15), (6,9,7,8)(11,15,13,12), (1,4)(3,5)(6,15)(7,12)(8,13)(9,11)(10,14)\rangle$
|
| Nilpotency class: | $2$ |
| Derived length: | $2$ |
The subgroup is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), metabelian, and rational.
Ambient group ($G$) information
| Description: | $D_5^2.C_2^2\times S_5$ |
| Order: | \(48000\)\(\medspace = 2^{7} \cdot 3 \cdot 5^{3} \) |
| Exponent: | \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \) |
| Derived length: | $3$ |
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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_5:D_5.A_4.C_4.S_5$ |
| $\operatorname{Aut}(H)$ | $C_2\wr C_2^2$, of order \(64\)\(\medspace = 2^{6} \) |
| $W$ | $C_2^2$, of order \(4\)\(\medspace = 2^{2} \) |
