چکیده
|
A c4c8 net is a trivalent decoration made by alternating squares c4 and octagons c8. it can cover either a cylinder or a torus. in this paper, we study the adjacency spectrum of rhomboidal c4c8 tori. we also give lower and upper bounds for a chemical quantity, namely estrada index, for a c4c8 net.
