FORMULA
|
a(n)= A005668(n)^2.
a(n)= 37*a(n-1) + 37*a(n-2) - a(n-3), n>=3; a(0)=0, a(1)=1, a(2)=36.
a(n)= 38*a(n-1) - a(n-2) - 2*(-1)^n, n>=2; a(0)=0, a(1)=1.
a(n)= (T(n, 19)-(-1)^n)/20 with the Chebyshev's polynomials of the first kind: T(n, 19)=A078986(n).
G.f.: x*(1-x)/((1-38*x+x^2)*(1+x)) = x*(1-x)/(1-37*x-37*x^2+x^3).
a(n)=-(1/20)*(-1)^n+(1/40)*[19-6*sqrt(10)]^n+(1/40)*[19+6*sqrt(10)]^n, with n>=0 [From Paolo P. Lava (ppl(AT)spl.at), Aug 27 2008]
