Abstract. In this paper, we give an algorithm that enables us to compute the neighbourhood of vertices of generalized tree obtained from a family of n stars having number of branches of those stars form an arithmetic progression (geometric progression) with common difference (ratio) j and one of the branches of each of those stars merged with one different point of a common path on n vertices successively in increasing order.
