The number 19 is a prime number.
Below are some polynomials that give prime numbers for small input values, which give the value 19 for suitable input choice.
|Polynomial||Degree||Some values for which it generates primes||Input value at which it generates 19|
|2||all numbers 1-16, because 17 is one of the lucky numbers of Euler.||2|
