 OFFSET 1,1 LINKS G. C. Greubel, Table of n, a(n) for n = 1..1000 Index entries for linear recurrences with constant coefficients, signature (4,-6,4,-1). FORMULA a(n) = 32*n^3 - 16*n^2 + 120*n - 60. G.f.: (60*z^3 - 12*z^2 + 68*z + 76)/(1-z)^4. a(n) = 4*a(n-1) - 6*a(n-2) + 4*a(n-3) - a(n-4). - G. C.
