Regarding your example, expanding the polynomial x^2 + x + 41.
Is there any way to PROOVE this is prime for
all integers x between 0 and 39 inclusive,
without actually testing or enumerating the range?
In other words, is this interesting fact unique or
the first of a sequence of such polynomials with
all values prime within a significant range?
That would be a nice puzzle to ask in this thread.
