FORMULA
G.f.: -(x^18 -6*x^17 +7*x^16 -13*x^15 +33*x^14 -178*x^13 +389*x^12 -567*x^11 +956*x^10 -6303*x^9 -956*x^8 -567*x^7 -389*x^6 -178*x^5 -33*x^4 -13*x^3 -7*x^2 -6*x -1) / (x^20 -291850*x^10 +1). - Colin Barker, Nov 29 2013
a(n) = 291850*a(n-10) - a(n-20) for n>19. - Vincenzo Librandi, Jan 12 2014
