1. Introduction DE Knuth [3, § 4.1; and in a private communication to RL Graham] has raised the question of describing, for a given positive integer b (which will be called the base, or radix), those finite sets D of real numbers with the property that every real number r can be represented in the form r=±2 aj)-*, fy= a^ r) e D.(1.1) i=-N (r)
