Abstract

In 1989, Erdős conjectured that for a sufficiently large nn it is impossible to place nn points in general position in a plane such that for every 1≤i≤n−11\le i \le n-1 there is a distance that occurs exactly ii times. For small nn this is possible and in his paper he provided constructions for n≤8n\leq 8. The one for n=5n=5 was due to Pomerance while Palásti came up with the constructions for n=7,8n=7,8. Constructions for n=9n=9 and above remain undiscovered, and little headway has been made toward a proof that for sufficiently large nn no configuration exists. In this paper we consider a natural generalization to higher dimensions and provide a construction which shows that for any given nn there exists a sufficiently large dimension dd such that there is a configuration in dd-dimensional space meeting Erdős' criteria.
