Basically we have a number of number of competitors (c) they have a race with any combination of the other competitors up to six at a time and each week they have a race a different set of people so what I was wondering is there a way using maths or anything of easily picking the racers so they race each other once in the compleat tornament
so say you have racers a-i
week one
race 1 a,b,c
race 2 d,e,f
race 3 g,h,i
week two
race 1 a,e,i
race 2 b,f,g
race 3 c,d,h
and so on
but unlike with small combinations like this it is really difficult when you have a large number to choose from to get each racer to have a race each week who hasn't raced a person before.

Yeah ital be you get so many points for a win and less for each place after but when ever I've tried to workit out we end up with racers who have raced twice.

hey bobbym
yeah the problem is me and a mate are thinking about starting a race seriers and we are going to have like 20 competitors ruffly and only about 5,6 that can run at a time but over the weeks we want each competitor to run every other competitor once. yeah I also know that some races will have less racers in than others but that doesn't matter
could you please help cheers
