This list proves that my Erdős number is smaller or equal than 2.

• Erdős, P., I. Joó, L. A. Székely (1987) Remarks on infinite series, Studia Sci. Math. Hung., 22: 395-400
• Hyunju Kim, Z. Toroczkai, I. Miklós, P. L. Erdős, L. A. Székely (2009) Degree-based graph construction, J. Phys. A., to appear.

(And please also note that my Erdős number of the second kind is one... :) )

On the other hand, I do not have a joint publication with Paul Erdős. Then my Erdős number is bigger than 1, hence it is 2.
