Plimpton 322 Refined: Reconstructing Missing Pairs in Babylonian Sexagesimal Triples — E8 Intelligence Research

FINDING: The search results are dominated by modern numerical interpolation pedagogy (Lagrange, splines, Newton forward) with only one substantive ancient-mathematics source — a paper on Plimpton 322 that refines Bruins' reconstruction of the tablet's generation scheme, explicitly addressing "missing pairs" and predicting subsequent entries. The modern videos are irrelevant to cuneiform specifics. MATH: - Plimpton 322 contains 15 rows of Pythagorean triples (a² + b² = c²) in sexagesimal, typically generated via reciprocal pairs (p, q) with a = p² − q², b = 2pq, c = p² + q². - Bruins' scheme uses regular sexagesimal reciprocals (n, 1/n) to produce triples. The paper's modification (arXiv:1109.3814v2) introduces a "natural" parameter shift that accounts for the gaps between rows — likely a linear spacing in the generating angle or in the ratio p/q, not a fixed one-degree step (no evidence of 1° spacing in the abstract). - No explicit equations are given in the search snippet; the Author: Andrew Stewart Caldin, Independent Researcher, UK.
