Then all these x's that cannot be used are all 1(mod 3)
and all the remaining x's will not produce all primes but
will have many composites among the primes.
So all x's that qualify ((a) not a multiple of 3 for (a)n)
but not necessarily prime are all the 0(mod 3) and all the 2(mod 3).
So the formula x^2+x+1 are for x is either a 0(mod 3) or
a 2(mod 3) and will produce a results that is a 1(mod 3)
and not by a long shot they are all prime.

If I am interpreting this correctly, what is your point?
