You're right, I did mean digraph. Sofs is a great module with the worst 
documentation available *unless* you already know set theory pretty 
well, then it translates pretty directly to the mathematical concepts.

But pick a random wikipedia page for a mathematical concept or theorem 
you know little about, and it will be likely as readable -- or less so 
-- than sofs is for people not in the know for set theory.
