 OFFSET 1,3 COMMENTS 62 is the smallest number not in this sequence. LINKS Robert Price, Table of n, a(n) for n = 1..2328 Eric Weisstein's World of Mathematics, Prime-Generating Polynomials EXAMPLE 4 is in this sequence since abs(1/4 (n^5 - 133n^4 + 6729n^3 - 158379n^2 + 1720294n - 6823316)) = abs((1024 - 34048 + 430656 - 2534064 + 6881176 - 6823316)/4) = 519643 is prime.
