perplexus.info :: General : Avoiding lattice midpoints

Avoiding lattice midpoints (Posted on 2017-08-27)

If two lattice points in the plane are chosen and joined by a line segment, the midpoint of this segment may or may not also be a lattice point.

Suppose you try selecting a set of points so that for every pair, the midpoint is not a lattice point.

Is there a limit to how many points you can pick?
