The Erdős Number Project website, run by Jerry Grossman at Oakland University, has updated its data files, for the first time since 2010.
Robert Bailey will be pleased, since he is now recognised as not the same person as Rosemary Bailey and “officially” has Erdős number 2.
I should also be pleased, since I am now on the list of Erdős coauthors with the most co-authors of my own (145, putting me equal 16th along with Laszlo Lovász and Vojtech Rödl). (As I explained here, I have 154 coauthors, or 172 if you count papers on the arXiv, but several of these don’t satisfy the stricter rules for collaboration that Grossman requires.)
Everyone else should be pleased since it is obviously important to have up-to-date information. Thanks to Jerry for what must have been a huge job!
