Cool, apparently I'm 4.

You are all twos!

Not fair, I was three when he died

PS The MS link is (predictably) not working for me. "Sorry, there is no path exist." (sic)

PPS Apparently one of the math professors here has an Erdös-Bacon number of 3 (with an Erdös number of 1).

PPPS https://files.oakland.edu/users/gros...np/Erdos1.html <-- A list of all people with Erdös number <= 2 (apparently xilman and bdodson have 2 paths to Erdös (and RDS has 3)). Further ^F'ing indicates both A Kruppa and J Gilchrist have E==2. ...As do Franke and Kleinjung and "the other Paul".

So it will have to be >1.

Cool! Looks like I'm no greater than 5 through multiple paths.

Edit: Maybe. Some of these connections look sketchy...

During my studies 20-25 years ago I wrote many (30? 50?) assembler little-programs, which used to illustrate different aspects of the course we were studying that time. There was the time when the PCs started to spread in our area, and everybody was very enthusiastic about. The little programs circulated for years during computer labs at the university, because they were well written and commented, and some of the assistants used them to teach younger students. Twenty years later, a former colleague of mine who is now professor there decided to write a book on assembler and put my programs inside (he asked me first, and I was quite pleased to find out someone still kept that stuff! I had lost it long ago with one of my hard disks which went nuts, and I was really happy to get back ALL of my archives, compressed by my own hand, this guy kept everything on floppies!) and he put me on the cover, together with some other people from which he took different other texts, source code, etc.

It turns out those "some other people" are very prolific authors in math and programming, and they cope with very low Erdos numbers... So I am definitively a 6, through multiple paths too, and I may be a 5 or even a 4, if the data base from Batalov's link would be more complete.

I have Erdős number 3 via multiple routes.
(I am used to checking the Erdős number of people from MathSciNet. Also, I don't have Silverlight (nor Moonlight) installed on this computer.)

ps. I now checked the MS-website with my desktop computer and there are just enormous gaps in the data (when compared to MathSciNet; after further looking into that MS-thingy it seems that some authors have multiple personalities... which cuts the coauthor chains). So, indeed it only gives some upper-bound (and it might use academic papers outside math, which are not considered when one calculates the Erdős number, so it only gives an upper-bound on the collaboration distance - not Erdős number.)

"3 is the loneliest number you will ever do
4 is just as bad as 3,
It's the loneliest number since number 5..."

one of my good friends exchanged guacamole recipes with Kevin Bacon at the Trader Joe's in Granada Hills. That's like two degrees.

Oh, sorry wrong thread.

Yes, each of us have co-authored witth SSW and PLM.

I'm also 5.
