Many members of the club disliked the lack of variety and togetherness at the club. Although the club still had 12 members, some members were threatening to quit because each schedule was so short and there were so few people around each table.

To satisfy their request, the club decided to seat themselves around a big table and create a longer schedule. The twelve members of the club seated themselves in a schedule such that during each block of 55 days, no person was between the same pair of people. How was the schedule constructed?

Wow. Congratulations on solving this puzzle! (If you're still around to hear it...) I read through all 61 comments (eventually) reading people quitting at the puzzle, failing computer programs and generally people getting frustrated at the fact that it took 7 months (yes, more than half a year!) to finally solve the puzzle.

Even if you aren't here anymore (because I don't recognize your name), congratulations!
