The people with Erdos numbers 1 and 2 are listed online. No one bothers with the 3s, because there are so many of us. (Sniff!)
Yes, I'm a 3 ... Erdos -> Nesetril -> Robin Thomas -> me.
Interestingly enough ... I had a cold when Erdos was vising UNL, and Earl Kramer asked whether I wanted to be introduced. I declined, deciding that it would probably not look good if I ended up being the person who gave Erdos a cold which killed him. (I saw him at Georgia Tech a couple of times, including once about a month before he died.
Ine of these times was when I had been invited to GT for graduate school, and Dad and I were checking out the place. When we walked by an office, Craig Tovey was explaining something to Erdos, who looked almost asleep. In fact, Dad later said that he wanted to yell out, "He's not paying attention to you! He's asleep!" Of course, I later told him who the almost-asleep guest was ...)
