(report abuse )
A Sierpinski number is an odd number k such that k.2^n +1
is not prime for any n > 0. A prime Sierpinski number is
a prime number k such that k.2^n +1 is not prime for any n
> 0. The smallest known prime Sierpinski number is
k=271129. Finding a prime of type k.2^n+1 for all primes k
less than 271129 will be sufficient to prove that 271129 is
the smallest prime Sierpinski number. The prime Sierpinski
problem consists of finding these primes.
