Resolving set and exchange property in nanotube

Give us a linked graph, $G=(V,E).$ A vertex $w\in V$ distinguishes between two components (vertices and edges) $x,y\in E\cup V$ if $d_G(w,x)\ne d_G(w,y).$ Let $W_1$ and $W_2$ be two resolving sets and $W_1$ $\ne$ $W_2$. Then, we can say that the graph $G$ has double resolving set. A nanotube derived from an quadrilateral-octagonal grid belongs to essential and extensively studied compounds in materials science. Nano-structures are very important due to their thickness. In this article, we have discussed the metric dimension of the graphs of nanotubes derived from the quadrilateral-octagonal grid. We proved that the generalized nanotube derived from quadrilateral-octagonal grid have three metric dimension. We also check that the exchange property is also held for this structure.
