FORMULA
a(n) = A136123(n,4). - Emeric Deutsch and _Vladet Jovovic_, Dec 17 2007
Conjecture: D-finite with recurrence (n-8)*(n-9)*a(n) -(n-9)*(n^2-6*n-2)*a(n-1) +(2*n^3-33*n^2+143*n-118)*a(n-2) +(5*n^2-27*n+16)*a(n-3) -2*(n-5)*(n-3)*(n-4)*a(n-4) +(n-5)*(n-3)*(n-4)*a(n-5)=0. - R. J. Mathar, Jul 01 2022
