In anycase, it has been proved that there is indeed an integral
polynomial that gives primes whenever it takes positive values.

I do not have an idea of the explicit form of the polynomial. Could
anyone enlighten me on this?

: See Hall & Knight Vol II (The title is "Higher Algebra" or some such thing). The proof
: is quite trivial.
