We study the infinite generation in the homotopy groups of the group of diffeomorphisms of , for , in a range of degrees up to . Our analysis relies on understanding the homotopy fibre of a linearisation map from the plus-construction of the classifying space of a certain space of self-embeddings of stabilisations of this manifold to a form of Hermitian –theory of the integral group ring of . We also show that these homotopy groups vanish rationally.
