My Erdos Number

My Erdös Number is 5.

Erdös numbers have been a part of the folklore of mathematicians throughout the world for many years.
Essentially, the Erdos Number Project studies research collaboration among mathematicians.

If you are curious about your Erdos number, you can compute it.

If you have written a paper with Paul Erdös, you have Erdos Number 1. If you are a coauthor of a coauthor, you have Erdös number 2. And so on.

Here is the mail I receive when I asked to compute my Erdos Number.
