Abstract
We give the standard expressions of the Zagreb indices, Randic indices and their variants. Then we present the master connectivity index and show how this index can generate all connectivity indices of both varieties. We also present the master connectivity polynomial and show the relationship between this polynomial and the master connectivity index. Because of this relationship, the master connectivity poynomial can also be used to generate connectivity indices.
