Harvey P. Dale, Table of n, a(n) for n = 0..900

Index entries for linear recurrences with constant coefficients, signature (26, -233, 844, -1056).

FORMULA

a(0)=1, a(1)=26, a(2)=443, a(3)=6304, a(n)=26*a(n-1)-233*a(n-2)+ 844*a(n-3)- 1056*a(n-4). - Harvey P. Dale, Jun 11 2012

a(n) = (5*11^(n+3)-14*8^(n+3)+30*4^(n+3)-21*3^(n+3))/840. - Yahia Kahloune, Jun 07 2013
