Determination of the order of the P-image by Toda brackets

The purpose of this talk is to try to determine the orders of Whitehead products [ιn] for n k + 2,k 24, where ιn is of the identity class of an n-sphere Sn and α is an element of the 2-primary components of the k-stem of the homotopy groups of Sn. We use the classical methods of homotopy theory, i.e. mainly the results of Kervaire, Mahowald, Mimura, Nomura, Oda and Toda.
