A NOTE ON PRODUCTS OF THE WHITEHEAD TYPE

Abstract A survey is given of various generalizations of the Whitehead product. Carrying the procedure a step further, a generalization is given that specialized in one wry relates to the “Whitehead elements” in the (mod p) kernel of the double suspension (p an odd prime, p > 4). Specialized in another way the product relates to the action of the Q-homomorphism (in the EHQ sequence) on elements that are not double suspensions.
