Lookup dissimilar word describer data

Hi excelers,
I be working on a formula for days now, and need help. The problem seems simple, but I can’t get any of my solutions to work.

I have encoded or classified 100 images into word describer blocks (30x10 array each). I simply need a formula that can search and find 10 unique word describer blocks, which are dissimilar from each other as equally as possible. As best as possible, one should have different characteristic words not find in each other, etc… see attachment.

I hope I have explained it as clearly as possible, if not, please let me know… and thanks for any help on this problem set…
