We propose the concept of quasi-random packing to represent the hierarchical random packing structure of clusters. We also find that the nematic order of clusters can be used to classify the ordered and disordered packing of tetrahedra, which is also an&amp;nbsp;&lt;/span&gt;indicator&lt;span&gt;&amp;nbsp;for quasi-random packing.&lt;/span&gt;&lt;/p&gt;</style></abstract></record></records></xml>
