Recently, some topological graph indices of pentagonal chains and pentagonal double chains are studied and here, we study some topological graph indices of pentagonal triple chains similarly to these previous works. We make use of the vertex and edge partitions of these graphs and calculate their indices by means of these partitions and combinatorial methods. Most of the indices calculated here are based on the degrees of adjacent vertices.
