12 golfers 4 rounds everyone plays with everyone

[georgeporter]

Hi

Any help greatly appreciated.

I have 12 golfers over 4 rounds playing in fourballs marking their own card (individual scores)

Day 1 has 3 additional golfers making 15 total for Day1
Day 2,3,4 played in 3 fourballs per day

Is it possible to arrange that everyone plays with everyone at least once over the four rounds?

The basic problem of 12 golfers and 4 rounds of fourballs has no solution where everyone plays once with everyone else.  The only practical option for the additional golfers on day 1 is to play together in their own threeball, if they were to be mixed in with the main 12 players then the number of pairs of players, who play together among the 12, would be even less.
