So I am preparing a convention with 28 persons. I want them to work in groups of 4 people (7 groups total) and regroup them 4 times without them meeting each other again. I can easily come up to 2 regroups, but it stops at 3. I have been searching all over the internet for apps or automatic calculators, but I can't find any. I think it is not possible to make this happen, but I need a way to minimize double meetups as much as possible. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 1 8 15 22 2 9 16 23 3 10 17 24 4 11 18 25 5 12 19 26 6 13 20 27 7 14 21 28
