[eikymeyu] Points not in general position

It can be arbitrarily difficult to detect if points are not in truly general position.  E.g., construct circumcenters of all triplets of points.  Show that no three points among the union of the original set and the circumcenters are on a line.

This could be the basis of a puzzle or maybe cryptography.

Previously vaguely similar
