  "abstract": "FINDING: Plimpton 322 is not merely a list of Pythagorean triples but encodes a systematic sexagesimal trigonometric table built from regular-number parameter pairs, with a missing-pair structure explained by a natural algorithmic constraint.\n\nMATH: - Tablet rows correspond to right triangles with sides \\((a, b, d)\\), \\(a < b < d\\), satisfying \\(a^2 + b^2 = d^2\\). - Bruins' reconstruction: parameters \\(p, q\\) (sexagesimal regular numbers, i.e., integers whose only prime factors are 2, 3, 5) generate triples via \\(a = p^2 - q^2\\), \\(b = 2pq\\), \\(d = p^2 + q^2\\) (or variants). - New insight (arXiv:1109.3814): missing pairs arise from requiring \\(p/q\\) to lie in a specific interval and \\(p, q\\) to be regular — the \"gaps\" are not errors but systematic exclusions. - Factor-12 algorithm (arXiv:2001.11141): proposes \\(b = M \\cdot Q_M\\), with \\(M, Q_M\\) positive integers, yielding a data-driven generative rule that reproduces all 15 rows exactly. - Trigonometric interpretation (arX\n\nAuthor: Andrew Stewart Caldin, Independent Researcher, UK.
