My Erdös number is at most 3.
Here's how: me –> Charles E. Hughes –> Stanley M. Selkow –> Paul Erdös
In other words,

• I published with someone
  • who published with someone
    • who published a paper with Paul Erdös.

Yes, many people have their own Erdös number, but it was still fun finding mine!
Here's one way I could lower my Erdös number.
