I cannot quite follow. What is an "isomorphismtype" for you? Earlier and 
also in your branch iso-experiments you do not use my view that 
isomorphismtypes should be represented as representatives of eqivalence 
classes. So not knowing which view you take I cannot say something precise.

Do you want to say {1,2} is *one* label?

Sorry, but I don't understand your mail. Maybe we should discuss this on 
Wednesday.
