%N If an array is made of columns of nacci sequences, fibo, tribo etc. all starting w. 1,1,2 etc, the NW to SE diagonals can be extended by computation. The above is diagonal 10. See A159741 for details.
%F Interpolate a(n)=(2*n^4+22*n^3107.5*n^2+276.5*n+1245)/3 offset 0 & b(n)=(2*n^418*n^3+77.5*n^2184.5*n+1713)/3 offset 0. Add a leading 89. Binomially transform. [From Al Hakanson (hawkuu(AT)gmail.com), Jun 08 2009]
%F a(n) = T(n+9,n+1) with T defined in A159741. a(n) = 2^(n+8)576 for n>=6.  _R. J. Mathar_, Feb 04 2021
