A000001 1+n^3+n^5 is prime

[Artur]

Related sequence to Zak's
%S A000001 1,1,2,1,2,1,10,2,2,1,2,1,48,182,2,1,60,1,10,42,2,1
%N A000001 Smallest number n such that 1+Sum(n^(2k-1)) is prime  
k=1,2,3,4,...
%C A000001 If number 1 occured in this sequence infinite times ?
%e A000001 a(7)=10 becuase n=10 is smallest prime number of the kind  
1+n+n^3+n^5+n^7+n^9+n^11+n^13=10101010101011
Polynomials 1+Sum(x^(2k-1)) aren't reducible
