Autor:  Erdös, Paul
Title:  Equidistant points in the plane. (In English)
Source:  Geombinatorics 4, No.2, 48 (1994).
Review:  Let f(n) be the largest integer for which there are n distinct points x1,...,xn in the plane so that for every i, 1 \leq i \leq n there are at least f(n) points xj, 1 \leq j \leq n equidistant from xi.
The author asks for an improved estimation for f(n) (and offers a price).
