RE: [math-fun] Erdos-Bacon number
Did Euler or Fermat ever have coauthors?

My Erdos Number is 2, and I was an extra in "A Beautiful Mind" (unfortunately not credited). So if I had gotten credit I would have 4 :-). Close, but no cigar.

Interesting questions: 1. What's the largest non-infinite Erdos number? Any estimates? Wild guesses? 2. What's the numerically longest string of back-references in math (or some other subject)? It might be limited by the average delay from writing to publication, so I'd guess a few hundred, going back to Gauss, Euler, or Fermat. I chose them because they presumably had little need to quote older work. True? False? Steve Gray

From http://en.wikipedia.org/wiki/Erdos_number " Amongst all working mathematicians at the turn of the millennium, the numbers range up to 15, but the average is less than 5, and almost everyone with a finite Erdos number has a number less than 8. According to Alex Lopez-Ortiz, all the <http://en.wikipedia.org/wiki//wiki/Fields_Medal>Fields and <http://en.wikipedia.org/wiki//wiki/Nevanlinna_Prize>Nevanlinna prize winners during the three cycles in 1986 to 1994 have Erdos number at most 9. "
It's a good thing I'm not included in the average or median because at an Erdos value of infinity, I would seriously distort those figures. Including people with 0 pubs would make too many values of infinity and REALLY foul up the figures. You can tell by this sophisticated post that I have had one or more publications in math.
