If I have 5 players in a whist style round robin, and want to get through all 15 possible match ups, is there a way to break it into three separate rounds with each player sitting out once each 5 games?
I can easily figure out the 15 match ups themselves, just not what order to put them in.
12 v 34
13 v 24
14 v 23
12 v 35
13 v 25
15 v 23
12 v 45
14 v 25
15 v 24
13 v 45
14 v 35
15 v 34
23 v 45
24 v 35
25 v 34
I can get the first round fine ...
12 v 34 (5 sits)
13 v 25 (4 sits)
15 v 24 (3 sits)
14 v 35 (2 sits)
23 v 45 (1 sits)
But I keep running into duplicate match ups in the second round.

Sorry to be the bearer of bad news, but I think it is impossible to partition the 15 match ups into three rounds.

That's kind of what I began to suspect. Can the first 2 rounds (10 games) follow that sort of pattern?
edit --
never mind. If the first 2 rounds follow that pattern, then the third round would follow by default.

24 35 bye 1

13 24 bye 5
34 25 bye 1
