    "abstract": "This paper aims to consider the general properties of the non-linear\nsolutions to the vacuum equations of Extended Electrodynamics. The *-invariance\nand the conformal invariance of the equations are mentioned. It is also proved\nthat all non-linear solutions have zero invariants: F_{\\mu\\nu}F^{\\mu\\nu} =\n(*F)_{\\mu\\nu}F^{\\mu\\nu} = 0. The three invariant characteristics of the\nnon-linear solutions: amplitude, phase and scale factor are introdiced and\ndiscussed.",
