This leads to a practical method for computing the homotopy groups of spheres. Moreover, it reduces the computation of the homotopy groups of (r+1)-sphere to a combinatorial group theory question. Keyphrases: Bouquet of spheres, Freudenthal suspension theorem, Hilton's theorem, James and Hilton-Milnor splittings, Necklace polynomials, Wedge sum, configuration space, homotopy groups, spheres
