FINDING: The Saros cycle (18 years, 11⅓ days) encodes a 120° longitudinal shift per cycle, creating a 3-fold symmetry in eclipse paths over 54 years (triple Saros). MATH: - Saros period = 223 synodic months ≈ 6585.321 days (18 years 11.321 days). - Earth rotation in that extra 0.321 days = 0.321 × 360° ≈ 115.6° → rounded to 120° (⅓ of full rotation). - Triple Saros (exeligmos) = 3 × 6585.321 days = 19755.963 days ≈ 54 years + 34 days, restoring same longitude (3 × 120° = 360°). - 223 synodic months = 242 draconic months (eclipse node alignment) + 239 anomalistic months (Moon's distance cycle). CONNECTION: - 120° shift per cycle = 3-fold rotational symmetry (C₃) in eclipse recurrence, aligning with crystallographic 3-fold axes and base-60 angular divisions (360°/3 = 120°). - Ratio 223/242 ≈ 0.9215, close to 0.922 (no direct golden ratio link, but 0.618/0.382 not present). - Exeligmos period (54 years) = 3 × Saros, mirroring triple symmetry in hexagonal lattices (e.g., Author: Andrew Stewart Caldin, Independent Researcher, UK.
