Vincenzo Librandi, Table of n, a(n) for n = 0..10000
Index entries for linear recurrences with constant coefficients, signature (9,-36,84,-126,126,-84,36,-9,1).
FORMULA
G.f.: -((390625*(x^8 + 6552*x^7 + 331612*x^6 + 2485288*x^5 + 4675014*x^4 + 2485288*x^3 + 331612*x^2 + 6552*x + 1))/(x-1)^9). - Harvey P. Dale, Nov 02 2011
From Amiram Eldar, Apr 18 2023: (Start)
a(n) = A017329(n)^8.
a(n) = 5^8 * A016760(n).
Sum_{n>=0} 1/a(n) = 17*Pi^8/63000000000. (End)
