Vincenzo Librandi, Table of n, a(n) for n = 0..10000
Index entries for linear recurrences with constant coefficients, signature (10, -45, 120, -210, 252, -210, 120, -45, 10, -1).
FORMULA
a(n) = 10*a(n-1) - 45*a(n-2) + 120*a(n-3) - 210*a(n-4) + 252*a(n-5) - 210*a(n-6) + 120*a(n-7) - 45*a(n-8) + 10*a(n-9) - a(n-10); a(0)=0, a(1)=2357947691, a(2)=1207269217792, a(3)=46411484401953, a(4)=618121839509504, a(5)=4605366583984375, a(6)=23762680013799936, a(7)=95151694449171437, a(8)=316478381828866048, a(9)=913517247483640899. - Harvey P.
