## Calculation of generalized Chebyshev polynomials

*Generalized Chebyshev polynomials* have been introduced in

**G.B.Shabat and I.A.Voevodskii**
- Drawing curves over number fields
* The Grothendieck
Festschift*, vol.3, Birkhäuser, 1990, pp. 199-227.

These polynomials are also known
as *Shabat polynomials*.
These polynomials are special case of
Belyi functions
At the end of 1990's I wrote a program for calculating generalized Chebyshev polynomials
and found a number of them. The method was oulined in
a short paper
and
two examples
were put on WWW.
A (slightly modified) version of
the program
is available.
