Abstract
Let be an equivalence relation defined on a finite group . The super commuting graph on is a graph whose vertex set is and two distinct vertices and are adjacent if either or there exist and such that commutes with , where is the -equivalence class of . Considering as the equality, conjugacy and same order relations on , in this article, we discuss the graph structures of equality/conjugacy/order super commuting graphs of certain well-known families of non-abelian groups viz. dihedral groups, dicyclic groups, semidihedral groups, quasidihedral groups, the groups etc. Further, we compute the Zagreb indices of these graphs and show that they satisfy Hansen-Vuki{\v{c}}evi{\'c} conjecture.
