Erdős problem 1082

Let $A\subset \mathbb{R}^2$ be a set of $n$ points with no three on a line. Must there exist a single point from which there are at least $\lfloor n/2\rfloor$ distinct distances?

This question has been answered negatively by Xichuan in the [comments](https://www.erdosproblems.com/forum/thread/1082), who gave a set of $42$ points in $\mathbb{R}^2$, with no three on a line, such that each point determines only $20$ distinct distances.

A smaller counterexample has been formalised here: it comprised of $8$ points, where each point only determines $3$ distances.

This counterexample has originally been found by Heiko Harborth.
