• Triangle T(n,k) read by rows: coefficients of polynomials P_n(t) defined in Formula section.at n=51A286785
• Triangular array read by rows: row n shows the coefficients of the polynomial p(x,n) constructed as in Comments; these polynomials form a strong divisibility sequence.at n=39A328644
• a(n) = p(2,n), where p(x,n) is the strong divisibility sequence of polynomials based on sqrt(5) as in A327322.at n=5A329013
