Abstract

Let A be a subset of the integer lattice Z n contained inside a sphere S in R n . Suppose that for each u ∈ S we know the number of points of A visible from u. Does this information determine the set A uniquely? In this note we answer this question affirmatively, provided the center of the sphere is not a rational point.
