G. Subashini, K. G. Ramanathan, K. Manimekalai · International Journal of Mathematics And its Applications · 2018
In this paper we prove that square sum labeling for $Py_n$; $(n \geq 3)$, $HPy_n$, $P(r, Py_n)$, $P(r, HPy_n)$, one point union of $r$ copies of pyramid and hanging pyramid graphs are square sum graphs by using Breadth First Search Algorithm.
