You also didn’t mention balancing the number of men and women in each group. That actually makes the problem a lot harder. The schedule below was found by computer. The 14 positions are the players, and the number in that position is the group number they play in. Groups 0 and 1 are foursome; groups 2 and 3 are threesomes.
My suggestion is to number the players so that 1, 3, 5, 7, … are women, and 2, 4, 6, 8, … are men. And it is probably wiser to ignore the group numbers and let the threesomes go out first. A weakness in this schedule is that player 1 is always in a foursome. A strength is that it is balanced as possible, meaning that the number of different pairs that get to play together is as large as possible. —Victoria
