Proth's theorem - Wikipedia

★ ★ ★ ☆ ☆

In number theory, Proth's theorem is a primality test for Proth numbers.. It states that if p is a Proth number, of the form k2 n + 1 with k odd and k < 2 n, and if there exists an integer a for which − ≡ −, then p is prime.In this case p is called a Proth prime.This is a practical test because if p is prime, any chosen a has about a 50 percent chance of working.

The Prime Glossary: Proth prime

★ ★ ★ ☆ ☆

So when seeking to settle the Sierpinski conjecture we look for a Proth prime for a fixed multiplier k. Finally, notice that we do not define any prime of the form k. 2 n +1 (with no restriction on the relative sizes of n and k) to be a Proth prime--because then every odd prime would be a Proth prime.
