Dear all
I have encountered a real life situation requiring some people good at maths to solve it.
Suppose there are 9 people, identified as 1,2,3,4,5,6,7,8,9
First step : three person as a group
1,2,3
4,5,6
7,8,9
then change partner but if previously as same group cannot be grouped together.
e.g.
1,4,7
2,5,8
3,6,9
then change partner again and if previously as same group cannot be grouped together.
How many groups can be formed and how to arrange these groups.
What will happen if there are 30 persons and 3 persons in a group each time.
The solution will be really useful for me.
Tommy
Thanks
