Abstract
We develop a method of estimating the (upper) density of a set in Rn or Sn for which the distance between any pair of points is not in a prescribed set. This is a generalisation of a planar principle of the first author. It improves the best known results for small values of n≥3. It also improves the known lower bounds on the measurable chromatic number of Rn for small n≥4.
