An old geometry problem discussed here asks for a finite set of points in the plane such that the perpendicular bisector of any 2 of the points contains exactly 2 of the points.
At last check there was just one known solution (up to rotation and scaling). In case anyone feels like looking for a solution, I won't mention the answer unless asked to.
Are there entries in OEIS that have just one integer, as in “number of points in known solutions to Dan’s problem”? You would have to add terms such as “bisector” to search such items. -Veit
