Abstract

The families of integral trees with 4, 6, 8 diameters were discussed. Most of these classes were infinite. Considering for a Graph G, V(G) denotes the vertex set of G and E(G) denotes the edge set various proofs were obtained. The construction of integral trees by identifying the centers of two trees was also elaborated.
