There are around 16M unique values. After accounting for equivalence,
the number is much smaller (I don't know how much smaller, since my
program has not completed yet :-)
Yes, I meant that "B and C are also equivalent". The original version
was a typo.

in the 20M pairs, how many unique values are there? In your statement
above " But equivalence is transitive, so if A and B occur together in
one pair, and A and C occur together in another pair, then A and C are
also equivalent.", did you mean that "B and C are also equivalent"?
