%N A050614 Products of distinct terms of A001566: a(n) = Product(L(2^(i+1))^bit(n,
               i),i = 0..[log2(n+1)]).
%C A050614 Each subset a[0..(2^k)-1] gives all the divisors of F(2^(k+1)) up to 
               k=4 (F_32) and after that a subset of such divisors. E.g. the terms 
               a(0)-a(7) are the divisors of F_16 = 987 (A018760)
