Subgroup ($H$) information
| Description: | $C_5\times C_{55}:C_{20}$ |
| Order: | \(5500\)\(\medspace = 2^{2} \cdot 5^{3} \cdot 11 \) |
| Index: | \(2\) |
| Exponent: | \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \) |
| Generators: |
$a^{5}b^{11}c^{8}, b^{10}, c^{2}, c^{5}, a^{2}, b^{22}c^{6}$
|
| Derived length: | $2$ |
The subgroup is characteristic (hence normal), maximal, a semidirect factor, nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.
Ambient group ($G$) information
| Description: | $C_{110}.C_{10}^2$ |
| Order: | \(11000\)\(\medspace = 2^{3} \cdot 5^{3} \cdot 11 \) |
| Exponent: | \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.
Quotient group ($Q$) structure
| Description: | $C_2$ |
| Order: | \(2\) |
| Exponent: | \(2\) |
| Automorphism Group: | $C_1$, of order $1$ |
| Outer Automorphisms: | $C_1$, of order $1$ |
| Derived length: | $1$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, and rational.
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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{55}.(C_{20}\times D_5).C_2^4$ |
| $\operatorname{Aut}(H)$ | $C_{55}.(C_{20}\times D_5).C_2^3$ |
| $W$ | $C_{110}:C_{10}$, of order \(1100\)\(\medspace = 2^{2} \cdot 5^{2} \cdot 11 \) |
