%N A099495 A Chebyshev transform of Fib(n)^2.
%C A099495 A Chebyshev transform of A007598, which has g.f. x(1-x)/((1+x)(1-3x+x^2)). 
               The image of G(x) under the Chebyshev transform is (1/(1+x^2))G(x/
               (1+x^2)).
%F A099495 G.f.: x(1-x+x^2)/((1+x+x^2)(1-3x+3x^2-3x^3+x^4)); a(n)=2a(n-1)-a(n-2)+3a(n-3)-a(n-4)+2a(n-5)-a(n-6); 
               a(n)=sum{k=0..floor(n/2), binomial(n-k, k)(-1)^k*F(n-2k)^2}.
