MOFTAKHAR University of Kashan, Iran Journal Article 2014 04 22 We derived explicit formulae for the eccentric connectivity index and Wiener index of 2-dimensional square-octagonal TUC4C8(R) lattices with open and closed ends. New compression factors for both indices are also computed in the limit N-->∞. 2-Dimensional square-octagonal lattice eccentric connectivity index Wiener index Topological compression factors https://ijmc.kashanu.ac.ir/article_5157_980a8f6666ab80bbd1230e6d506def34.pdf
