 But since "A" can take values bigger or smaller than 1, some polynomials, according to the conjecture, will be especially rich in primes, and others especially poor.An unusually rich polynomial is 4"x"2 − 2"x" + 41 which forms a visible line in the Ulam spiral.The constant "A" for this polynomial is approximately 6.6, meaning that the numbers it generates are almost seven times as likely to be prime as random numbers of comparable size, according to the conjecture.
