:a(n+2)=9602*a(n+1)-a(n)+2200, a(n+1)=4801*a(n)+1100+980*(24*a(n)^2+11*a(n)+1)^0.5. G.f.: f(z)=a(1)*z+a(2)*z^2+...= (z+21*z^2+2178*z^3+2178*z^4+21*z^5+z^6)/((1-z^2)*(1-9602*z^2+z^4)) (the numerator is divible by 1+z but it is more symetri" like that) - Richard Choulet (richardchoulet(AT)yahoo.fr), Oct 03 2007
