P. Moree, Convoluted convolved Fibonacci numbers

Formula

G.f.: (z/10)[1/(1-z-z^2)^10-1/(1-z^2-z^4)^5-1/(1-z^5-z^10)^2+1/(1-z^10-z^20)].

Maple

with(numtheory): f := z->1/(1-z-z^2): m := proc(r, j) d := divisors(r): W := (1/r)*z*sum(mobius(d[i])*f(z^d[i])^(r/d[i]), i=1..nops(d)): Wser := simplify(series(W, z=0, 80)): coeff(Wser, z^j) end: seq(m(10, j), j=1..40);

Mathematica

terms = 27; r = 10; f[z_] := 1/(1 - z - z^2);
W = (z/r)*Sum[MoebiusMu[d]*f[z^d]^(r/d), {d, Divisors[r]}]+ O[z]^(terms+1);
CoefficientList[W, z] // Rest (* Jean-François Alcover, Dec 09 2017, from Maple *)
