On Pierce-like idempotents and Hopf invariants by Giora Dula, Peter Hilton

“…Given a set K with cardinality ‖K‖ =n, a wedge decomposition of a space Y indexed by K, and a cogroup A, the homotopy group G=[A,Y] is shown, by using Pierce-like idempotents, to have a direct sum decomposition indexed by P(K)−{ϕ} which is strictly functorial if G is abelian. …”
