    Suppose nn points in R2\mathbb{R}^2 determine a convex polygon and the set of distances between them is {u1,,ut}\{u_1,\ldots,u_t\}. Suppose uiu_i appears as the distance between f(ui)f(u_i) many pairs of points. Then if(ui)2n3.\sum_i f(u_i)^2 \ll n^3.

    For every finite planar point set P, the sum over its distinct determined distances of the unordered-pair distance multiplicities equals P.card.choose 2

    • Decision performer: Accept the byte-identical Erdős 94 assertion as the current Submission v3 revision after two scoped actor-separated fidelity reviews. This removes only the obsolete recovery caveat, preserves the exact occurrence mapping and every scientific limit, and adds no new validation.
