I have a group of 27 students, and I want them to meet in groups of three in a sequence where each student is with each other student in a group exactly one time.
I know it should be possible. In 13 rounds, you meet 26 people. I need sequences, though, of which students are in groups together for each round.
I can't find a website that will do this for me. I have found several Round Robin tournament creators, but those produce results in pairs. I would like triads.
