And yet Taral would be wrong and Dave Feustel correct: http://mathworld.wolfram.com/Prime-GeneratingPolynomial.html There is a polynomial (of degree 25) in 26 variables which generates only primes whenever it is positive. Surprising, yes it is. Note that this polynomial is actually rarely positive! Jacques Taral wrote:
Not bloody likely.

I have heard that a generator function has been found that generates prime numbers directly using only addition and subtraction. There purportedly have been presentations of this information to selected mathematicians who have verified that the generator function works. But I haven't found any confirmation by googling. Has anyone got wind of this?
