7 men are going on a golfing holiday playing 4 rounds of golf. Always in a group of three and a group of 4. What is the best combination so all players get a fair chance to play with as many of the others as possible and also in a fair split of 3 and 4 man groups?

This should be moved to Homework Help.

Im not really bothered where it goes as long as I get an answer. Thank you.
