I am trying to solve a puzzle for my sporting event in which i want to equally place all matchups that variate enough without playing the sport more than twice (14 games per team in total) and also as much as possible with equal breaks during the games as 14 teams are playing at the same time and 6 teams are having a break in every round (20 teams total).
