Prime-Generating Quadratic of form x squared - 79 x + 1601

Theorem
The quadratic function:
 * $x^2 - 79 x + 1601$

gives prime values for integer $x$ such that $0 \le x \le 79$.

The primes generated are repeated once each.

Proof
Let $x = z + 40$.

Then:

Thus it can be seen that this is an application of Euler Lucky Number $41$.
