Exact classical solutions of Yang-Mills sourceless equations

Exact solutions of dual equations are found. They describe classical particle-like formations possessing the zero energy and imaginary electric and magnetic charges. Possible interpretation of the solutions is associated with the hypothesis discussed on the existence of two more vacuums, except for the trivial one, which are degenerated, complex-conjugated and characterized by the zero mean value of the charge and its negative rms value.
