On the complexity of platonic solids

The Platonic solids serve as very useful structural rnodels in chemistry. The tetrahedron is especially important Platonic solid because it is a key structural unit in organic chernistry and represents the basis of our understanding of structures, properties and reactivities of carbon cornpounds. As a cornplexity rneasure of Platonic solids, we used the number of spanning trees. They were calculated using formula based on the Laplacian spectrum of a molecular graph. Schlegel graphs are convenient graph-theoretical representations of the Platonic solids. The icosahedron and the dodecahedron possess the largest number of the spanning trees and thus they appear to be the most cornplex Platonic solids. However, sorne of their characteristics, e.g., the rnatching number or the Bertz information-theoretic index, predict the icosahedron to be the most cornplex Platonic solid while the other, e.g., the Z-index, preter the dodecahedron.
