Sierpinski conjectures
Definition
[edit | edit source]For the original Sierpinski problem, it is finding and proving the smallest k such that k×bn+1 is not prime for all integers n ≥ 1 and GCD(k+1, b-1)=1.
Extended definiton
[edit | edit source]Finding and proving the smallest k such that (k×bn+1)/GCD(k+1, b-1) is not prime for all integers n ≥ 1.
Notes
[edit | edit source]All n must be >= 1.
k-values that make a full covering set with all or partial algebraic factors are excluded from the conjectures.
k-values that are a multiple of base (b) and where (k+1)/gcd(k+1,b-1) is not prime are included in the conjectures but excluded from testing.
Such k-values will have the same prime as k / b.
