• First row of spectral array W(sqrt(5)-1).at n=22A022165
• a(0)=0, a(1)=1; for n>1, a(n) = 6*a(n-1)-4*a(n-2).at n=12A084326
• G.f. satisfies: A(x) = exp( Sum_{n>=1} [Sum_{k=0..2*n} A200536(n,2*n-k)^2 * x^k] / A(x)^n * x^n/n ), where A200536(n,2*n-k) is the coefficient of x^k in (2+3*x+x^2)^n.at n=37A251689
