28: 508:, combines Michel Deza's interests in polyhedral combinatorics and metric spaces; it describes the metric polytope, whose points represent symmetric distance matrices satisfying the triangle inequality. For metric spaces with seven points, for instance, this polytope has 21 dimensions (the 21 pairwise distances between the points) and 275,840 vertices. 289:-element set shared by all the members of the family. Manoussakis writes that Deza is sorry not to have kept and framed the US$ 100 check from Erdős for the prize for solving the problem, and that this result inspired Deza to pursue a lifestyle of mathematics and travel similar to that of Erdős. 218:
The papers from a conference on combinatorics, geometry and computer science, held in Luminy, France in May 2007, have been collected as a special issue of the European Journal of Combinatorics in honor of Deza's 70th birthday.
