A (p, q) graph G is said to admit a seventh (or eighth) order triangular sum labeling if its vertices can be labeled by non negative integers such that induced edge labels obtained by the sum of the labels of end vertices are the seventh (or eighth) order triangular numbers. A graph G which admits a seventh (or eighth) order triangular sum labeling is called a seventh (or eighth) order triangular sum graph. In this paper we prove that double star K 1,n,n , Tg n and Coconut tree admit seventhdoi:10.22457/apam.613v19n2a10 fatcat:cn7nnuihmzc3bgxybqrcmk2ieq
