This appears in some earlier listings and we must have just dropped a card at some sorting before the tables were lined up.

The non Hamiltonian graphs are coded as splicings of two (or more) circuits. The appropriate edges must be signified. See attached. No attempt has been made to scan the nonplanar, nonpolygonal graphs- I would be delighted to hear how you came out -in your synthesis.-'.Are- you thinking of building any gauche forms? Do you have some use for the complete set of graphs including trees and complexes? If so and you can describe the domain ingraph terms, I could easily generate the set and would be glad to. Sincerely yours, Joshua Lederberg Professor of Genetics JL:eif P.S. Did you recognize the truncated tetrahedron as BFBFBB? .i .~ .._
