Title:  CC systems and vortex-free tournaments

Abstract:   A CC (counterclockwise) system is a relation on triples of points, satisfying five axioms inspired by the orientations of points in the plane. We will introduce these axioms and their causes, and then introduce the tournaments that can be used to represent CC systems and visualize the axioms. These tournaments are all vortex-free, which we will define, learn how to generate, and count.
