Dear SeqFans,
I formulated the following conditional Theorem (two in one):
If all Sierpinski numbers are dual and all Riesel numbers are dual,
then, for any odd prime p and for any integer m >= 0,
there exists a number n >= 0 such that |(p-/+2^m)2^n+/-1| is prime.
Corollary: If p < q is a pair of twin primes,
then there are natural numbers m,n such that
the both numbers p2^m+1 and q2^n-1 are prime.
Has anyone noticed it before?
Best regards,
Thomas Ordowski
