The graph is the best manifestation of thesystem by depicting it as a topological structure. The most studied graph invariant is the atom-bondconnectivity index to identify and investigate the topological aspects of interconnection networks. Inthis work, firstly, we identify vertices for different families of n-vertex networks with complete graphsof any order to obtain a new transformation network. Analogously, we get a variety of transformedgraphs. Finally, we provide the extremal results regarding the ABC index for the transformationgraphs under discussion.
