[Nauty-list] Detecting isomorphic collections in the Boolean lattice

[Kevin Gilbert]

Hi,

I am trying to use nauty test whether two collections of sets from the Boolean 
lattice are isomorphic. For example, I want some way for nauty to tell me 
that the collections 123, 124 and 134, 135 are isomorphic.

I have tried various colouring schemes, canonical labelling & etc without any 
success.

So I am left with these questions: (1) Can nauty be used in this fashion? (2) 
If so, how?

Thanks in advance for any assistance,

Kevin
