Four symmetries, which are needed for the determination of a diffraction group by convergent-beam electron diffraction (CBED), were obtained from one selected-area CBED pattern. An inversion symmetry and a four-fold inversion symmetry were observed by selectedarea CBED technique. Coherent CBED patterns show the phase information of crystal structure factors. The phase relations between crystal structure factors for a non-mirror symmetry, a mirror symmetry and a glide symmetry were observed by coherent CBED.
