Index entries for linear recurrences with constant coefficients, signature (6,-15,20,-15,6,-1).
FORMULA
G.f.: (3125 + 230082*x + 1029982*x^2 + 694762*x^3 + 58857*x^4 + 32*x^5)/(x-1)^6. - R. J. Mathar, Jul 14 2016
a(n) = 6*a(n-1) - 15*a(n-2) + 20*a(n-3) - 15*a(n-4) + 6*a(n-5) - a(n-6). - Wesley Ivan Hurt, Jan 01 2024
