Index entries for linear recurrences with constant coefficients, signature (26, -233, 820, -900).
FORMULA
a(0)=1, a(1)=26, a(2)=443, a(3)=6280, a(n)=26*a(n-1)-233*a(n-2)+ 820*a(n-3)- 900*a(n-4) [From Harvey P. Dale, Jul 12 2011]
a(n) = -2^n/21 +25*5^n/12 -729*9^n/28 +25*10^n/1. R. J. Mathar, Jun 20 2013
