# Schinzel's hypothesis H

Suppose  are all irreducible polynomials with integer coefficients and with positive leading coefficient, such that the product  does not have any fixed divisors, i.e., it cannot be expressed as a proper multiple of an integer-valued polynomial. Schinzel's hypothesis H states that there are infinitely many natural numbers  satisfying the condition that  are all simultaneously prime.
