%N Prime factors of 3^(3^n) + 2.
%C The last entry is 3^(3^5) + 2, a probable prime. Conjecture: These numbers have no repeating factors or 3^(3^n) + 2 is squarefree.
%C The Magma Calculator (http://magma.maths.usyd.edu.au/calc/) confirms that the term given above for a(13) is, in fact, prime. - _Jon E. Schoenfield_, Aug 24 2009
