a(n) = a(n-48) for n > 47.

G.f.: x^2*(-7*x^45 - 5*x^43 - 7*x^42 - 6*x^41 - 7*x^40 - 8*x^39 - x^38 - 9*x^37 - 6*x^36 - 9*x^35 - 2*x^34 - 2*x^33 - 4*x^32 - 7*x^31 - 5*x^30 - 5*x^29 - 3*x^28 - 9*x^27 - 8*x^26 - 3*x^25 - 3*x^24 - 7*x^23 - 4*x^22 - 3*x^21 - 8*x^20 - 6*x^19 - 8*x^18 - 7*x^16 - x^15 - 7*x^14 - 2*x^13 - 9*x^12 - 7*x^11 - x^10 - 8*x^9 - 4*x^8 - 4*x^7 - 2*x^5 - x^4 - x^3 - 8*x - 2)/(x^48 - 1).
