I am trying to create an unique kind of sports schedule. It is fairly large and I believe really difficult. There will be 135 teams involved with a round robin format. (Every team will play each other once). However I am trying to set in a 17 week period. I am trying to set it up with 15 groups of 9 with 9 rounds on four venues. Meaning 1 of the 9 will have a bye in each round. Can anyone help?
