Groups of self-homotopy equivalence for various spaces are calculated. If $X$ is a finite CW-complex we derive a spectral sequence converging to ${\rm Aut}(X)$. If $X=X_1 \times X_2$ is a product of two spaces we express ${\rm Aut}(X)$ as a product of subgroups depending on factors. When $X$ is a universal space of a secondary cohomology operations ${\rm Aut}(X)$ is described by the groups of homomorphisms between modules over the Steenrod algebra.
