I want to make a playing schedule for 32 players (teams) that play for 8 months.
Each month four teams player each other.  Is it possible to make a schedule and have no two teams play each other more than once?
Also, keeping numbers 1-8 in the first column, 9-16 in the second column, etc.

example: 1   9  17  25    play together
              2  10  18  26
              3  11  19  27
              4  12  20  28
              5  13  21  29
              6  14  22  30
              7  15  23  31
              8  16  24  32

I think I need a miracle.

Thank You!

It is possible to do this -  no miracles required!

I guess you have split your 32 players in to 4 teams or groups and you want to arrange it so that each game has one member from each team?
