“…He defined a suborbital graph Gi corresponding to the suborbital Oi ⊆ X × X as a graph whose vertex set is X and edge set E consists of directed edges from x to y where (x, y) ∈ Oi. Since then, there has been an intensive study on these graphs by several researchers including; [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], among others.…”
