We seem to have lost the display of this number in the message views. It is still there in the individual profiles.

Do we only include papers written in calculating an Erdos number?

I've co-authored a book with someone who has an Erdos number, but I've not written any papers.

I don't think it includes textbooks, especially ones that is elementary or semi-elementary, only research papers (think there is also a rule that says up to two collaborators).

If you google erdos calculator I think ams or maa has a website that calculates it for you, assuming it's been published long enough.

According to https://en.wikipedia.org/wiki/Erd%C5%91s_number it is only erdos numbers of the 2nd kind that can only have up to two collaborators.

The calculator is at https://mathscinet.ams.org/mathscine...html?version=2
It isn't perfect. I haven't made it on there yet although I have collaborated with someone with an Erdos number of 4. I may be better than 5 but I am not going to check all my collaborators from a paper with >100 authors.

It is a book about two years of study of and reflection on the work of Caleb Gattegno's concept of Awareness in mathematics education. I wouldn't call it a 'textbook' but you might be using a broad definition of that term.

"The Atlas Collaboration"
Because filling front pages of a paper with a list of 3000 coauthors is bad form.
https://arxiv.org/pdf/1207.7214.pdf
https://atlas.cern/discover/collaboration

Or CMS at 4000 participants, with 1000+ papers https://cms.cern/collaboration

Thank you! That's the free distribution service I was thinking about in the other thread.

Neato!

Mine is 4 by multiple routes:

Vladimir S. Shevelev
Jean-Paul Allouche
Gérald Tenenbaum
Paul Erdős

Peter J. C. Moses
Curtis N. Cooper
Hang Chen
Paul Erdős

Vladimir S. Shevelev
Jean-Paul Allouche
Jean-Marc Deshouillers
Paul Erdős

Peter J. C. Moses
Clark Kimberling
Aviezri S. Fraenkel
Paul Erdős

Silly, since they all go through the same paper.

Oakland University has an interesting set of pages about Erdős Number facts, statistics and trivia.

BTW, mine = 3 [via Erdős -> Pomerance -> Crandall], but note my user profile displays sqrt(5) ... I had hoped to eventually publish something with Peter Montgomery[1] re. our explorations of fast hybrid floating-point/modular Galois transforms, but life, career and the evolution of actual CPU architectures led to that never happening. I still have a set of detailed notes Peter typed up summarizing the work we had done dated circa 2000, so I suppose there's still a tiny chance of eventually publishing that in some short summary form despite Peter's having passed, thus the sqrt(5) reflects my moments of unwarranted optimism on that point. :)

In order to win a lottery, you need to buy a ticket.
@ Raman - Get on a paper or a few.

Mine is 3 (and many folks in bioinformatics can say the same, if they were on any of the whole genome consortiums where E.Lander (=2) was a member).
