An effective five-wave Hamiltonian for one dimensional water waves on the
surface of an infinitely deep ideal fluid is presented. The diagrammatic
technique is used. For some particular orientations of wave vectors
the interaction matrix element is exactly zero, while for others it is
given by remarkably simple formulaes. This is another miracle
of water wave theory.
