I need a individuals pairs schedule for 14 players. Where every player pairs with each other one time, plays against every other play twice, and all players get 2 byes. It should be 14 rounds with the byes. This is a NON Asymmetric schedule. I would like to find a generator for 6,10,14,18,22,26,and 30 players. Any help would be greatly appreciated.

What you are asking for is actually impossible. Suppose there are 14 rounds and 14 players with 2 byes per round, then each player has exactly 12 games. This means that every player has at least one other who is never a partner, and at least two others who they oppose only once.  Add a 15th round and things are no better, it might or might not be possible (I don't know which) for 12 of the players to meet your criteria, however the remaining 2 players who have a bye in the 15th round will have one game less than everyone else.  The same issues apply with the other numbers of players that you mention.

Thanks for responding! You are exactly right. I realized it after I posted . I need a schedule or a formula that matches your first example. Where everyone plays 12 matches and gets 2 byes. Then it would work the same for 18, 22, 26 ETC.. The reason the byes have to be equal is the 2 players with byes in a certain round would play singles against each other. So all players would play 12 doubles matches and 2 singles matches. Can you help? Thanks again.
