Cofinality of Regular Tournaments

Combinatorics 2026-05-07 v1

Abstract

We show that the class of all finite regular tournaments is cofinal in the class of finite tournaments. In addition, we establish cofinality results for certain special subclasses of regular tournaments. We also provide an algorithm for constructing these regular tournaments.
