Erdős was one of the most prolific mathematical writers. He worked with many mathematicians. Paul Erdős's number is 0. Anyone who directly worked with Paul Erdős has an Erdős number of 1. Anyone who works with those collaborators who have an Erdős number of 1, has an Erdős number of 2. The chain continues like that. ==Related pages== * [[Bacon number]] ==Other websites== * Jerry Grossman, [http://www.oakland.edu/enp The Erdös Number Project].
