Sorry for the confused question... it is the result of a confused
mind. I have many thousands of observations (zip codes and telephone
exchanges to be precise) and there are a lot more groups than 2 (in my
example there was one unique combo and everything else being groups).
I don't know how many "legs" the biggest group has but will look at
Michael's code to see if I can get it to work.
Thanks Scott and Mikael for your responses!
