My Erdös Number

My Erdös number is 4. This is derived in two independent ways.

The first way is with my frequent coauthor Don Pigozzi. This path is:

• Gary T. Leavens: 4
• Don Pigozzi: 3
• Jiri Sichler: 2
• Laszlo Babai, Ervin Fried, Zdenek Hedrlin, and Jaroslav Nesetril: 1
• Paul Erdös: 0

The second way is with Kim B. Bruce:

• Gary T. Leavens: 4
• Kim Bruce: 3
• Albert Meyer: 2
• Daniel J. Kleitman: 1
• Paul Erdös: 0

See the Erdös project database for an explanation of this.
