Leveling groups

[jawon]

I don't even know correct terminology for this type of work so I'll try to explain...

1. I have about 50 groups that each have a varying number of people in them. For example, GroupA=100, GroupB=50, etc.

2. I would like to assign them each into one panel within a 3x3 matrix in a way where all the panels have about the same number of people in them.

I'm hoping there is some SAS procedure to identify the best combination of groups, or at least some programmatic way to handle this. Any ideas would be appreciated.
