  "abstract": "FINDING: The Sumerians chose base-60 (sexagesimal) for its superior divisibility and computational efficiency, enabling exact handling of reciprocals, fractions, and large numbers in a positional system. | MATH: 60 = 2² × 3 × 5; divisors of 60: {1,2,3,4,5,6,10,12,15,20,30,60} — 12 total, giving exact terminating sexagesimal fractions for all reciprocals of numbers whose prime factors are ≤5 (e.g., 1/2=0;30, 1/3=0;20, 1/4=0;15, 1/5=0;12, 1/6=0;10, 1/8=0;7,30, 1/9=0;6,40, 1/12=0;5). Regular numbers (5-smooth) have finite sexagesimal expansions. | CONNECTION: Base-60 is the lowest number with 12 divisors (highly composite); its prime factors {2,3,5} generate the 5-smooth lattice — directly linked to the crystallographic root system of A₄ (tetrahedral symmetry, order 60) and the icosahedral/dodecahedral symmetry group (also order 60). The ratio 60/37.5 = 1.6 (near φ=1.618) and 60/97.5 ≈ 0.615 (near 0.618) emerge in sexagesimal divisions; 1/60 = 0.01666… and 60×0.618 = 37.08 (close to 37;30\n\nAuthor: Andrew Stewart Caldin, Independent Researcher, UK.
