Nonassociativity as a generating source of the mass levels of hadrons and leptons

Grading is performed to the proper Lorentz algebra. Nonassociativity appears in the process of grading. Geometrical progression of mass value of hadrons and leptons is explained as the results of the quantization mechanism through nonassociativity. It is suggest to take the fundamental unit lenght as the quantization of nonassociativity
