I'll share how I would approach a diagram for this game. This is a pretty tough game to diagram since there arent really any "fixed" spots, since the teams change their order
We have six people: M, N, O, P, S, T and three teams who will be ranked 1-3: F G H
I would set up two diagrams- a "master" diagram showing who ranks where, and a secondary diagram showing who is on what team.
