In a series of papers, Imran et al. reported the total eccentricity index, the average eccentricity index, the eccentricity-based Zagreb indices, the atom-bond connectivity index, and the geometric arithmetic index of honeycomb networks, hypertrees, X-trees, and oxide networks. In this paper, it is demonstrated that these computations contain flaws. Corrected, and in many cases also simplified, formulas are also obtained.
