Primes of the form 1 + A191554(k), associated with positions k=1, 2, 3, and 5 there. The next one (if it exists) occurs at k>=15 and has >53500 digits. [Edited by R. J. Mathar, Jun 17 2011 and Joerg Arndt, Jun 21 2011]
This connects A191554 and A191555, which are deeply about primes and monic polynomial irreducible by Eisenstein's Criterion, to primes by another way, connecting additive and multiplicative number theory analogously to the relationship in Primorial primes: A014545, n such that nth Euclid number (A006862(n)) = 1 + (Product of first n primes) is prime.
