A person's Erdös Number, named after the prolific mathematician
Paul Erdos, is the length of the shortest chain of co-authored,
referred papers from the person to Erdös. It follows then that
Erdös' own Erdös number is 0, anyone that has co-authored with
Erdös has an Erdös number of 1, and so on.

There is also an Erdös Number of the second type, in which only
papers with exactly two authors count. This is much more
restrictive.
