Any mathematicians on line, I need to solve this problem? 8 golfers, so two fourballs, playing over 5 rounds. I need to to get all playing at least twice with each golfer. The best I can come up with is playing 3 times with 4 Golfers and once with 3 golfers. E.g. Golfer A plays 3 times with B,C ,E and F but only once with C,D and G Hope you get what I mean as my brain is now fried. Hole in one to the smart arrse who comes up with a better solution.
