<jats:p> We discuss a set of novel discrete symmetry transformations of the [Formula: see text] supersymmetric quantum mechanical model of a charged particle moving on a sphere in the background of Dirac magnetic monopole. The usual five continuous symmetries (and their conserved Noether charges) and two discrete symmetries together provide the physical realizations of the de Rham cohomological operators of differential geometry. We have also exploited the supervariable approach to derive the nilpotent [Formula: see text] SUSY transformations and provided the geometrical interpretation in the language of translational generators along the Grassmannian directions [Formula: see text] and [Formula: see text] onto [Formula: see text]-dimensional supermanifold. </jats:p>
