G. C. Greubel, Table of n, a(n) for n = 0..1000
Index entries for linear recurrences with constant coefficients, signature (0,0,0,0,0,0,1).
FORMULA
From R. J. Mathar, Apr 20 2010: (Start)
a(n) = a(n-7).
G.f.: ( -1-7*x-20*x^2-24*x^3-23*x^4-16*x^5-25*x^6 ) / ( (x-1)*(1+x+x^2+x^3+x^4+x^5+x^6) ). (End)
