Title: Team golf schedule
Post by: golfnut on October 16, 2010, 05:22:53 PM
 Is there a schedule for 36 golfers where the foursomes change every round and you never have the same players on the same team until the cycle repeats?

It is not possible to have everyone playing with everyone else exactly once.  However you can play 11 rounds without any repeated pairs, so everyone would play with 33 of the 35 possible opponents exactly once.

Hope that helps.

36 Golfers, 9 groups of 4, 11 Rounds
