FORMULA
|
Given g.f. A(x), then B(a) = A(q) / q satisfies 0 = f(B(q), B(q^2)) where f(u, v) = v - u * (u - 2). - Michael Somos, Oct 22 2013
Euler transform of length 3 sequence [ 1, 0, -1]. - Michael Somos, Oct 22 2013
G.f. is third cyclotomic polynomial.
G.f.: (1 - x^3) / (1 - x).
|
|
EXAMPLE
|
G.f. = 1 + x + x^2.
G.f. = 1/q + 1 + q.
