(color online) (a) The occurrences of the 20 most popular Voronoi indices for Zr (Cu/Ni) in a glassy state. The indices are sorted by the coordination number as shown on the top of the figure. In the icosahedral cluster distribution in Zr Cu (b) and Zr Ni (c), the dark gray balls represent the icosahedral clusters.
