Bloch wave degeneracies, which can be observed in high-energy electron diffraction, are summarized. Many beam dynamical theory and the symmetries of Bloch waves are described briefly for discussion of Bloch wave degeneracies. Conditions for degeneracy of Bloch waves are explained for the three-beam case. Degeneracies in the symmetric three beam case and non-systematic reflections case are shown. Critical voltage in systematic row of reflections is discussed.
