The Conversing Club (Posted on 2003-12-29) Difficulty: 4 of 5
There are 10 tables in the Conversing Club and 15 members. Each day, 3 people sit together around each of 5 of 10 possible tables in the club talking to each other.

Every week (7 days) everyone is at the same table with everyone else exactly once. Also, nobody is at the same table twice in the course of a week to provide a change of scenery each time. The first day is as following:


(The second day A couldn't sit with B, or C; B couldn't sit with C; D couldn't sit with E or F, but could sit with A, B, or C.)

How could their schedule be configured?

I see that my table-assignment algorithm is not preventing some people from visiting the same table twice. I don't have time to correct that right now, but I'll work on it later.
