Elliptic Fibrations on Vinberg's Most Algebraic K3 Surface
arXiv:2311.11766
Abstract
We explain how to use the computer algebra system OSCAR to find all elliptic fibrations (up to automorphism) on a given surface and compute their Weierstrass models. This is illustrated for Vinberg's most algebraic K3 surface, the unique K3 surface of Picard rank 20 and discriminant 3.
