Аннотация:
A classical hypergeometric function $\{\}_n F_{n-1)(\alpha,\beta,t)$ and an auxiliary prime number determine a Belyi map. We will give an overview of this class of Belyi maps, and why it is important to explicitly compute them. To illustrate this theory, we present a new computation of a degree 120 hypergeometric Belyi map with monodromy group $Sp_8(F_2)$.
