Given n people, you can arrange n(n−1)/2 matches between them. If n is even, you can do n−1 rounds of n/2 matches; if n is odd, n rounds of (n−1)/2 matches. https://en.wikipedia.org/wiki/Round-robin_tournament#Scheduling_algorithm #math #co

What “combinatorics” means
Wiktionary · Wikipediacombinatorics
- nounA branch of mathematics that studies (usually finite) collections of objects that satisfy specified criteria
Combinatorics is an area of mathematics primarily concerned with counting, both as a means and as an end to obtaining results, and certain properties of finite structures. It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science.
