Mixed individual-pairs tournament design for 9 players

This 9-player individual-pairs tournament design, last updated in April 2004, is based on an original by Matt Fayers of The Department of Mathematics at Queen Mary, University of London (formerly of The Department of Pure Mathematics and Mathematical Statistics at The University of Cambridge).

There is also a pure 9-player design, consisting of 9 rounds, each of which has two games of two-versus-two and one player having a bye. But in this much slower mixed design, each of the 12 rounds consists of three games of two-versus-one.

Properties of this tournament design:
