Harvey P. Dale, Table of n, a(n) for n = 0..925
Index entries for linear recurrences with constant coefficients, signature (29,-280,972,-720).
FORMULA
a(n) = (30*12^(n+3) - 55*10^(n+3) + 33*6^(n+3) - 8)/3960. [Yahia Kahloune, Jun 28 2013]
a(0)=1, a(1)=29, a(2)=561, a(3)=9121, a(n)=29*a(n-1)-280*a(n-2)+ 972*a(n-3)- 720*a(n-4). - Harvey P. Dale, Apr 20 2015
