My Erdös Number

From my best calculation, my Erdös number is 4. The path is:

Path Edge	Publication
Erdös -> Nesetril	Paul Erdös, Jaroslav Nesetril , Vojtech Rodl, "A remark on Pisier type theorems," Congres. Numer. 113 (1996), 102-109.
Nesetril -> Jezek	Jaroslav Jezek, Jaroslav Nesetril, "Ramsey varieties," Europ. J. Combinatorics 4 (1983), 143-147.
Jezek -> Maroti	Jaroslav Jezek, P.Markovic, Miklos Maroti, R. McKenzie, "Equations of tournaments are not finitely based," Discrete Math 211 (2000), no. 1-3, 243-248.
Maroti -> Gray	Gabor Karsai, Miklos Maroti, Akos Ledeczi, Jeff Gray, and Janos Sztipanovits, "Composition and Cloning in Modeling and Meta-Modeling Languages," IEEE Transactions on Control System Technology, special issue on Computer Automated Multi-Paradigm Modeling, March 2004, pp. 263-278.

Here is a 5-path:

5. Jeff Gray
4. Murali Sitaraman
3. Bruce Weide
2. Michael Fredman
1. Daniel J. Kleitman
0. Paul Erdös

An even older path had me at 6:

6. Jeff Gray
5. Murali Sitaraman
4. Gary Leavens
3. Kim Bruce
2. Albert Meyer
1. Daniel J. Kleitman
0. Paul Erdös

See the Erdös project database for an explanation of this.
