Abstract: 

The notion of N-type axis of symmetry is introduced. It is proved that the vector field defined by system of the differential equations with norder polynomials in a right hand, cannot have even number of axes of symmetry N-type at n =2m,m ∈N. For n =2,3 full research of the given system on N-symmetry is carried out. Depending on the number of axes of N-type symmetry special forms of presenting of square and cubic systems, which allow to simplify qualitative research of such systems, are discovered.
