title: Comment on "Families and clustering in a natural numbers network".
abstract: Corso [Phys. Rev. E 69, 036106 (2004)] constructs a family of graphs from subsets of the natural numbers, and numerically estimates diameter, degree and clustering. We give exact asymptotic formulas for these quantities, and thereby argue that number theory is a more appropriate tool than simulation.
