# Rotating teams without repeating [closed]

I have 24 teams that will rotate to 12 stations (2 teams per station) Teams will not compete against another team more than once.

• Not clear. What it the question? Sep 19, 2017 at 19:52
• Instructions unclear. Rotated station and it is now upside down. Sep 19, 2017 at 20:07
• This team builder is for 24 teams. I have 12 stations for the teams to rotate through. There will be 2 teams competing at each station. How do i rotate all of the teams through all of the stations competing against teams only once. Sep 19, 2017 at 20:19
• Can one team visit the same station multiple times? And how many matches does each team need to play? Also, please see the question that I linked in my earlier comment, because yours is very similar and it may provide an answer for you. Sep 19, 2017 at 20:38

On the $i$th round, for $i$ = 1, 2, ..., 23, have team 24 play against team $i$. For the other teams, divide them into pairs so that in each pair, the line connecting the two teams is perpendicular to the line connecting team $i$ to team 24. This means that team i – 1 plays i + 1, team i – 2 plays i + 2, and so on, where addition is modulo 23.
