Subgroup ($H$) information
| Description: | $C_{11}\times D_{10}$ |
| Order: | \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \) |
| Index: | \(14\)\(\medspace = 2 \cdot 7 \) |
| Exponent: | \(110\)\(\medspace = 2 \cdot 5 \cdot 11 \) |
| Generators: |
$a, b^{140}, b^{924}, b^{770}$
|
| Derived length: | $2$ |
The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, and an A-group.
Ambient group ($G$) information
| Description: | $C_{11}\times D_{140}$ |
| Order: | \(3080\)\(\medspace = 2^{3} \cdot 5 \cdot 7 \cdot 11 \) |
| Exponent: | \(1540\)\(\medspace = 2^{2} \cdot 5 \cdot 7 \cdot 11 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and hyperelementary for $p = 2$.
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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{70}.C_{30}.C_2^5$ |
| $\operatorname{Aut}(H)$ | $D_{10}:C_{20}$, of order \(400\)\(\medspace = 2^{4} \cdot 5^{2} \) |
| $\operatorname{res}(S)$ | $D_{10}:C_{20}$, of order \(400\)\(\medspace = 2^{4} \cdot 5^{2} \) |
| $\card{\operatorname{ker}(\operatorname{res})}$ | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
| $W$ | $D_{10}$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \) |
