G. C. Greubel, Table of n, a(n) for n = 0..1000
Index entries for linear recurrences with constant coefficients, signature (0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1).
FORMULA
From R. J. Mathar, Feb 06 2011: (Start)
a(n) = a(n-23).
G.f.: (-1-2*x-4*x^2-8*x^3-16*x^4-32*x^5 -17*x^6-34*x^7 -21*x^8-42*x^9 -37*x^10-27*x^11-7*x^12-14*x^13 -28*x^14-9*x^15 -18*x^16-36*x^17 -25*x^18-3*x^19 -6*x^20-12*x^21-24*x^22 ) / ( (x-1)*(1+x+x^2 +x^3+x^4+x^5 +x^6+x^7+x^8 +x^9+x^10+x^11 +x^12+x^13+x^14 +x^15+x^16+x^17 +x^18+x^19+x^20+x^21+x^22) ).
