A094477 Primes of form 2^n + 37^n. 0

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

%S 2,1373,1874177,

%T 23169162752708970943114627382699355445603465075569066753527132965271355336698663708393617779709970177

%N Primes of form 2^n + 37^n.

%C The number n must be zero or a power of 2. Checked n being powers of two through 2^20. Thus a(5) > 10^3200000. Primes of this magnitude are rare (about 1 in 7.5 million), so chance of finding one is remote with today's computer algorithms and speeds. - _Robert Price_, Apr 29 2013

%Y Cf. A094473, A094474, A082101, A094476.

%K nonn

%O 1,1

%A _Labos Elemer_, Jun 01 2004

%E No more terms for n < 1000, so the next term will be too large to include. - _Hugo Pfoertner_, Aug 17 2004
