Let t(n, d) be the minimum number t such that there are t of the nd lattice points {Mathematical expression} so that the (2t) lines that they determine cover all the above nd 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.
