The Topological Information Superindex

A comparative analysis of the discrimination power of eleven indices (see Table 1, all indices but J) indicated 88) that no index so far described discriminates isomers uniquely. 

A combined topological index, named superindex, SI, consisting of a number of topological indices was, proposed.88 Three versions of SI have been presented  

Considering the very low degeneracy of index J (the last one in Table 1) in comparison with the other topological indices, a fourth approach seems possible, namely the summation of only two topological indices, J and %, which provides complete discrimination of all known structures.
