COMMENTS

No additional terms through j=1000. - Harvey P. Dale, Apr 24 2013

The number j must be zero or a power of 2.  Checked j being powers of two through 2^19. Thus a(5) > 10^2300000. Primes of this magnitude are rare (about 1 in 5.4 million), so chance of finding one is remote with today's computer algorithms and speeds. - Robert Price, May 05 2013
