 OFFSET 1,1 COMMENTS This polynomial f(n) generates 19 prime numbers consecutively (for n=0 to n=18). In n^2 + n + 17, substitute n -> n^3 - 24*n^2 + 166*n - 318. The polynomial f(n) generates 10790 primes in the first 100000 values. - Stefan Steinerberger, Apr 21 2006 REFERENCES Paulo Ribenboim, The Book of Prime Number Records.
