147.0. "A 7 pt problem of Erdos" by HARE::STAN () Fri Sep 14 1984 13:05
Erdos asks: Can you find 7 points in the plane
such that one distance appears once, one two times, ..., one 6 times?
No three points should be on a line, no four on a circle.

| Since the problem asks for 7 points, rather than 6 or 5, I assume that there
is a known solution for 6 points. Could it be supplied here?

| I don't have the original article, only a review of it (from Math Reviews).
So readers: can you find a solution with 6 points?
