摘要
We construct a convex set A with cardinality 2n and with the property that an element of the difference set A - A can be represented in n different ways. We also show that this construction is optimal by proving that for any convex set A, the maximum possible number of representations an element of A - A can have is left perpendicular vertical bar A vertical bar/2right perpendicular.
