• Icosahedral quasicrystals were examined by convergent-beam and small-area-parallel-beam electron diffraction. Advances in the quality of Icosahedral quasicrystals were described. It was found that an alloy of Al_<70>Pd_<20>Mn_<10> has the best qualified icosahedral phase at present. The space group of an icosahedral phase of Al_<74>Mn_<20>Si_6 was determined to be a centrosymmetric Pm<35>^^^-, although small breakdown of symmetry was observed.
