Points 4, 8, 7, 3, 10, 14, 9, 13, 5 I have them somewhere. There is a low-res image in Research Problems in Discrete Geometry by Brass Moser Pach. --Ed Pegg Jr On Mon, Sep 17, 2018 at 1:10 PM Allan Wechsler <acwacw@gmail.com> wrote:
For a given set of k points in the plane, some number n of the mutual distances are 1. How big can we make n for a given k? A186705 at OEIS given the answers we know, but only up to 14 vertices.
Where can I see pictures of example maximal unit distance graphs? The first "surprise" is a(9)=18; I would love to see that one. _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com https://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
