- There is a conjecture known as Sierpinski-Schinzel conjecture H stating the
- following:
-
- Let irreducible polynomials f1,f2,...,fn have the property
- that there is no m > 1 such that for every x
- m | f1(x)f2(x)...fn(x)
-
- Then there exist infinitely many numbers x such that all
- f1(x) , f2(x) , ... , fn(x) are prime.
-
- It follows from the above conjecture that there are infinitely many twin or
- quadruple primes.
-
-
- The conjecture has been formulated in
-
- Sur certaines hypotheses concernant les nombres premiers, Acta Arith. 4 (1958)
- pp 185-208.
-
- Note that there is a misprint there as the essential word "irreducible" has
- been skipped. The correction appears ibidem 5 (1959) p 259.
