Hi all

You may or may not have seen my thread looking to start a league... if not please check it out! (shameless plug)

Gathering a wee bit of interest. But I need a maths genius to help with the fixture list.

In my head the amount of people in the league will have to be a multiple of 7. But that may or may not be true. I am looking for a set of fixtures that:

1. Ensures everyone in the league plays all the other participants once, but;

2. No-one should play the same player 3 or more times (twice is acceptable)

3. Everyone should play the same amount of games (hence me thinking you want a multiple of 7)

4. The number of games per person should ideally be 3 or 4 each.

Is this doable. I don't mind if the odd person doesn't play everyone and only plays 18/20 of the other contestants. That (in my mind) is better than someone playing the same player in all 3 (or 3/4) of their games.

I feel like there should be a clever way of working this out, but it is escaping me. If you have any clever ideas please post of PM me!

Thanks

Mike
