The positive-only integer series from the proximate-prime polynomial (PPP) 2n2 - 2n + 53089 produces 634 primes in the first 1000 terms. This is more than for any other PPP derived from 4 successive primes under 1000000. As comparison, 582 primes are generated by the quadratic n2 - n + 41. [Capelle]
