We compute bounds on covering maps that arise in Belyi's Theorem. In particular, we construct a library of height properties and then apply it to algorithms that produce Belyi maps. Such maps are used to give coverings from algebraic curves to the projective line ramified over at most three points.
A classical theorem of Stafford says: every left ideal of partial differential operators with rational or even polynomial coefficients in n variables can be generated by two elements. The highly involved proof of this theorem is reorganized and completed for rational coefficients in order to yield a
