A094478 Primes of form 2^j + 59^j. 0

%I #12 Oct 15 2013 22:32:24

%S 2,61,12117377,

%T 464798130469793589516643498190087912509935907401081390977

%N Primes of form 2^j + 59^j.

%C The number j must be zero or a power of 2. 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 j=0: p=1+1=2;

%e j=1: p=2+59=61;

%e j=4: p=16+12117361=12117377;

%e j=32: p=2^32+59^32=464798130469793589516643498190087912509935907401081390977;
