Wiener-index on rows of unit cells of the face-centered cubic lattice

What is it about?

Wiener-index is the first topological index which can be used to measure the compactness of molecules and also to predict some of their physical and chemical properties. The face centered cubic (fcc) lattice is one of the most known crystallographic structure. In the paper, the Wiener index of graphs representing fcc unit cells connected to each other in a line is computed. According to the increasing number of unit cells, an integer sequence is also computed.

Why is it important?

Graph indices can be used as structure descriptors, thus, it is good to know how to compute them for various graphs that are connected to structures of various materials.
