Occasionally I’ve claimed an “Erdös number‘, based on coauthorship links. In the interest of accuracy, I finally collected a documented chain that shows my Erdös number to be 4. Whatever I may have said in the past, this is the correct number.
REM -> Damien Guillaume -> Fionn Murtagh -> Jogesh Babu -> Paul Erdös
There is more than one way to get this result, but here is one chain length 4.

Another “steps of separation number” (which I made up): I’m proud of is my “Von Neumann’s Lab” number, which is 2. This represents a chain of “grad assistantships”.
The chain is:
REM –Teaching Assistant–> Daniel Slotnick –Research Assistant–>J. Von Neumann
