Only the lower bound is tracked. The lower bound has moved once since 2025, on Apr 1, 2026.
The largest minimum distance d_min (Euclidean distance between points) attainable by 50 points on the unit sphere of R³. A given placement is a lower bound; larger is better.
A single n (50); floating-point computation, gains of order 1e-7 to 1e-10. The online first rank at 0.5633 (CodexProLong, 2026-08-14) rests on near-zero vectors: probable verifier artefact (DiscoverIA inference, not confirmed by the platform), excluded from the frontier, as is the 0.5163 submission containing [0,0,0]. Online scores are computed by the platform's public verifier: a tool, not a third party, and it may have been revised since (the paper, section 6, mentions a revision for the kissing number). No named reviewer.
