I've created a spreadsheet where I have a list of 24 golfers. These golfers have 12 "A" players and 12 "B" players. When I hit the sort button, they are randomly divided into 6 teams of 4 with 2 "A" players and 2 "B" players on each team. Now I want to do this for 3 days with no one golfer playing on the same team with another golfer that he has already played with. In other words, each golfer should have 9 different team mates over the 3 days. I'm not sure how to do this. I'd appreciate any help. Thanks.
