There are 44 players on 11 tables - people are moving around - What I would
like to know is who has played with whom - example from round 1 and 2
(detail below)

Player 1 has played with 12, 23, 34, 21, 25, and 44.
Player 12 has played with 1, 23, 34, 3, 27, and 35.

How can I do this - By the way players 1 - 11 can move (for this example I
kept them fixed?

Thanks in advance.
