Wonder if anyone can help me out. My girl have started in school, and the (we) parents have agreed that we want to setup play-groups of 4 kids into each group. Plan is that the group should swoop so that all kids will play with each other 3 times each. It should be possible within 20 rounds/dates.
The time frame is every 2. week, but that is not relevant as I will change the dates/weeks to consider vacaton/holidays etc.
What I need is a good plan on how I can ensure all kids have played with each other approx 3 times each.
Can anyone help me out here ?
