Abstract

Let t(n, d) be the minimum number t such that there are t of the n^d lattice points {Mathematical expression} so that the (₂^t) lines that they determine cover all the above n^d lattice points. We prove that for every integer d≥2 there are two positive constants c₁=c₁(d) and c₂=c₂(d) such that for every n {Mathematical expression} The special case d=2 settles a problem of Erdös and Purdy.
