Alcon,
Concerning the sequence A112299: Expansion of x(1-x)(1-x^2)(1-x^3)/(1-x^8) in powers of x, shouldn't the sequence be prepended with a(0)=0?
Since the sequence cycles {0, 1, -1, -1, 0, 1, 1, -1} how does the comment work?
The title and the cited G.f. in the Formula line are not quite equal.
Bob.
