Abstract: Let $ M$ be a closed flat Riemannian manifold, $ \varepsilon (M)$ the group of self homotopy equivalences of $ M$. Then there exists a subgroup $ {A_1}(M)$ of $ \operatorname{Aff} (M)$ such that the natural homomorphism of $ {A_1}(M)$ into $ {\pi _0}\varepsilon (M)$ is a surjection with kernel a finite abelian group. Furthermore, this kernel can be identified with the structure group of the Calabi fibration.
