Uma amostra dos trabalhos publicados:

O mais antigo: On the Boolean matrix equation , Journal of the Association for Computing Machinery 12 (1965), 376-382.

O mais citado: On subgraphs as matroid cells, Mathematische Zeitschrift 127 (1972), 315-322.

O que me deu mais prazer: An algorithm and its role in the study of optimal graph realizations of distance matrices, Discrete Mathematics 79 (1990), 299-312.

O mais (injustamente) insultado: Just two total graphs are complementary (co-autoria com Fernando Escalante), Monatshefte fuer Mathematik 81 (1976), 5-13.

O mais esquecido: Matroidal families of graphs, em:"Matroid Applications" (ed.: Neil White), pg. 91-105, Encyclopedia of Mathematics and its Applications 40, Cambridge University Press, 1992.
