I want to make a tournament bracket. I want it like this:

12 people to start with (one from each pair will advance),

6 people in the second round but in the second round, each group has 3 people (2 from each trio will advance),

4 people in the third round (one from each pair will advance),

2 in the finals, and then the winner.

But I don't know how to do it. Does anyone know how you do it?
