The problem of decomposition of a projective collineation into special harmonic homologies i.e. homologies with the fixed center and homologies with fundamental hyperspaces containing the fixed points, is considered. We prove that for every harmonic homology of the n-dimensional projective space there exists j < 3 such that the ha.rmonic homology is a product of j harmonic homologies from the given class.
