Ajitha, Arumugam, and Germina defined the square sum graph. A graph G = (V,E) with order p and size q is said to be a square sum graph, if there exists a bijection mapping f∶ V (G) → {0,1,2,...,(p - 1)} such that the induced function f^*: E(G) → N defined by f^* (uv)=(f(u) )^2+(f(v) )^2 , for every uv ∈ E(G) is injective. The graph which admits square sum labeling is called a square sum graph. This paper establishes Square sum labeling on the super subdivision of crown and coconut tree.
