For example, Andrew Wiles has Erd??s number at most 3, because he is a coauthor of Chris M. Skinner, who has written with ANDREW ODLYZKO, who has written with Erd??s. (Warning: your number, if greater than 2, might decrease over time, especially if you or your colleagues write more papers!) If you want help computing your Erd??s number, contact Jerry Grossman (see above)
