# Carry-Over tournament design for 14+14=28 players

Julian D. A. Wiseman, March 2002

This is a carry-over tournament design for 14+14=28 players. It therefore assumes that two qualifying leagues (called ‘Roman’ and ‘Italic’) have played an all-play-all, and that the top 14 players from each are through to the final. In the final these 28 players are then to play each other, except that games already played between them are ‘carried over’. The players in the Roman league are called A, B, C, etc, and those in the Italic league a, b, c, etc.

It was last updated in March 2002, and 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).

• Each player plays exactly once each of the players in the other league.

• Each player plays exactly once at each venue.

• Each player plays seven times on each side (left and right).

• It is seeded, so that important games come late in the tournament. It is assumed that player A is better than B, etc, and that a is better than b, etc. (Usually rankings are determined by the players’ scores in the qualifying rounds.)

• It has a permutation score of 31576.7615459055305109359, which is either maximal or near-maximal.

• It has a left-right asymmetry measure of 91307/3710266560 = 0.000024609283, which is either minimal or near the minimum.
