## Calculation of Belyi functions

performed by Yuri Matiyasevich
In 2016 I wrote a program for calculating Belyi functions for trees with weighted edges. Here are results of some calculations.

Trees from orbits 12.3, 12.8, 12.9  from paper by N. Adrianov and A. Zvonkin. These trees are of interest because of the actions of Mathieu groups $$M_{12}$$ on them.
