Skewes Numbers for Twin Primes and the Hardy-Littlewood Constant — E8 Intelligence Research

FINDING: The Hardy-Littlewood k-tuple conjecture predicts the asymptotic density of prime constellations via a singular series constant; the twin-prime constant C₂ ≈ 1.90216058 emerges as the leading factor for pairs (n, n+2), with recent computational work locating "Skewes numbers" where the predicted count reverses relative to actual counts. MATH: - Twin prime constant: C₂ = 2 ∏_{p≥3} [1 − 1/(p−1)²] ≈ 1.902160583104… - Hardy-Littlewood asymptotic for k-tuples (admissible set H = {h₁,…,h_k}): π_k(x; H) ~ 𝔖(H) · x / (log x)^k where 𝔖(H) = ∏_p [ (1 − 1/p)^(−k) · (1 − ν_p(H)/p) ], ν_p(H) = number of distinct residues of H mod p. - For twin primes (k=2, H={0,2}): 𝔖 = 2C₂. - Skewes number for twin primes: first x where π₂(x) < predicted value (Wolf, 2011); extended to 8 more k-tuples in arXiv:1910.02636. CONNECTION: - The constant C₂ = 1.90216058… is *not* a classical golden-ratio multiple, but note: C₂ / π ≈ 0.6055 (near 0.618, golden ratio conjugate, within 2% Author: Andrew Stewart Caldin, Independent Researcher, UK.
