  "abstract": "FINDING: The Sumerian/Babylonian choice of base-60 (sexagesimal) is not arbitrary but a practical, number-theoretic optimization for divisibility, enabling efficient arithmetic with large integers and fractions. | MATH: Base 60 = 2² × 3 × 5. Key property: 60 has 12 divisors (1,2,3,4,5,6,10,12,15,20,30,60). This yields reciprocals terminating in base-60 for all numbers of form 2^a·3^b·5^c (a,b,c ≤ 2,1,1 respectively). Compare: base-10 has only 4 divisors (1,2,5,10). The sexagesimal system encodes the regular numbers (5-smooth numbers) as finite expansions. | CONNECTION: Base-60 directly links to the 5-fold and 6-fold symmetries of crystallography and icosahedral/dodecahedral groups. The divisors {2,3,5} are exactly the primes generating the root lattice A₄ (icosahedral symmetry) and the 60-element rotational icosahedral group (A₅). The ratio 60/360 = 1/6, and 60° is the interior angle of an equilateral triangle — the fundamental tile of the hexagonal lattice. | DEPTH: 7\n\n---\n\nFINDING: S\n\nAuthor: Andrew Stewart Caldin, Independent Researcher, UK.
