The symmetry present in molecules is a fundamental concept in Chemistry. Group Theory is an extremely powerful tool which, in spite of abstractness provides the systematic treatment of symmetry of molecules that simplifies the process of obtaining a variety of information about molecules. Molecules are classified according to their symmetry properties. In this paper, analyzing all the symmetry operations as well as symmetry elements of Sulphur-hexa–floride (SF6) molecule, the authors determine the point group and its abstract presentation as α2 = β4 = (αβ)6 = 1〉
