In this paper one studies the local topological structure of analytic mappings. It is proved that the complement in the space of all germs of analytic mappings from $\mathbf C^n$ to $\mathbf C^q$ of the set of germs whose topological type is unchanged under alteration of large terms of the Taylor series has infinite codimension.
