Subgroup ($H$) information
| Description: | $C_{11}^2:C_3$ |
| Order: | \(363\)\(\medspace = 3 \cdot 11^{2} \) |
| Index: | \(1100\)\(\medspace = 2^{2} \cdot 5^{2} \cdot 11 \) |
| Exponent: | \(33\)\(\medspace = 3 \cdot 11 \) |
| Generators: |
$b^{22}, d^{5}, cd^{50}$
|
| Derived length: | $2$ |
The subgroup is characteristic (hence normal), a semidirect factor, nonabelian, monomial (hence solvable), metabelian, and an A-group.
Ambient group ($G$) information
| Description: | $C_{11}^2:C_{165}:C_{20}$ |
| Order: | \(399300\)\(\medspace = 2^{2} \cdot 3 \cdot 5^{2} \cdot 11^{3} \) |
| Exponent: | \(660\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \cdot 11 \) |
| Derived length: | $3$ |
The ambient group is nonabelian, monomial (hence solvable), and an A-group.
Quotient group ($Q$) structure
| Description: | $C_{220}:C_5$ |
| Order: | \(1100\)\(\medspace = 2^{2} \cdot 5^{2} \cdot 11 \) |
| Exponent: | \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \) |
| Automorphism Group: | $D_{110}:C_{20}$, of order \(4400\)\(\medspace = 2^{4} \cdot 5^{2} \cdot 11 \) |
| Outer Automorphisms: | $C_2^2\times F_5$, of order \(80\)\(\medspace = 2^{4} \cdot 5 \) |
| Derived length: | $2$ |
The quotient is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 5$, and an A-group.
Automorphism information
Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{11}^3.C_{15}.C_{10}^2.C_2^4$ |
| $\operatorname{Aut}(H)$ | $F_{121}:C_2$, of order \(29040\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \cdot 11^{2} \) |
| $W$ | $C_{11}^2:(C_5\times S_3)$, of order \(3630\)\(\medspace = 2 \cdot 3 \cdot 5 \cdot 11^{2} \) |
