Try this:Here's what I need. 16 golfers put into 4 foursomes every day for five days. Need every golfer to play with each other golfer only once example: Day 1 (Joe -Skip-John-Pete) Day 2 (Joe -Scott - Jason- Harry) Day 3 ( Joe - Craig - Dave -Ken) Day 4 ( Joe - Zilly - Chris - Ed) Day 5 ( Joe - Steve- Walt - Dan) after 5 days Joe has played with every one.
