Checked j being powers of two through 2^21. Thus a(5) > 10^2900000. Primes of this magnitude are rare (about 1 in 6.7 million), so chance of finding one is remote with today's computer algorithms and speeds. - _Robert Price_, Apr 28 2013 %e A094478 j=0: p=1+1=2; %e A094478 j=1: p=2+59=61; %e A094478 j=4: p=16+12117361=12117377; %e A094478 j=32: p=2^32+59^32=464798130469793589516643498190087912509935907401081390977; %e A094478 the j exponents are powers of 2. %Y A094478 Cf.
