Plimpton 322: Sexagesimal Reciprocal-Pair Generation of Pythagorean Triples — E8 Intelligence Research

FINDING: Plimpton 322 contains systematic generation of Pythagorean triples, likely using a reciprocal-pair method based on sexagesimal (base-60) arithmetic. | MATH: For a pair of reciprocals \(p\) and \(q\) (with \(p > q\)), the triple is \((a, b, c)\) where \(a = p^2 - q^2\), \(b = 2pq\), \(c = p^2 + q^2\). The tablet lists \(a/c\) and \(b/c\) ratios, with \(c\) always a regular sexagesimal number. Key constants: 1;24,51,10 (approximation of \(√2\) to 6 sexagesimal places), 0;45 (3/4), 0;30 (1/2). | CONNECTION: The method relies on base-60 regular numbers (numbers whose reciprocal is a terminating sexagesimal fraction), which are intimately tied to the lattice structure of the Babylonian number system. The ratios \(a/c\) and \(b/c\) approximate values like 0.618 (golden ratio conjugate) and 0.786 (related to \(√φ\)), though not explicitly listed. The sexagesimal system itself is a base-60 positional system, which naturally generates harmonic ratios through its regular Author: Andrew Stewart Caldin, Independent Researcher, UK.
