%N A147558 Result of using the Fibonacci numbers as coefficients in an infinite 
               polynomial series in x and then expressing this series as (1+a(1)x)(1+a(2)x^2)(1+a(3x^3)...
%e A147558 From the Fibonacci numbers, beginning 1,1, construct the series 1+x+x^2+2x^3+3x^4+5x^5+... 
               a(1) is always the coefficient of x, here 1. Divide by (1+a(1)x), 
               i.e. here (1+x), to get the quotient (1+a(2)x^2+...), which here 
               gives a(2)=1. Then divide this quotient by (1+a(2)x^2), i.e. here 
               (1+x^2), to get (1+a(3)x^3+...), giving a(3)=1.
