  We procure the complete set of (anti-)BRST as well as (anti-)co-BRST symmetry
transformations of the Friedberg-Lee-Pang-Ren (FLPR) model within the framework
of the supervariable approach. Additionally, we capture the nilpotency and
absolute anti-commutativity aspects of these symmetries, along with the
invariance of the Lagrangian in terms of translational generators along the
Grassmannian directions in the context of the supervariable approach. The
anti-commutator of the (anti-)BRST and (anti-)co-BRST symmetries generates a
novel bosonic symmetry that retains the ghost part of the Lagrangian invariant.
Furthermore, we demonstrate that the system under consideration respects the
ghost scale and discrete symmetries, in addition to other symmetries. We show
that the generators of all these symmetries cling to the algebra obeyed by the
de Rham cohomological operators of differential geometry - thus, the FLPR model
presents a toy model for the Hodge theory.
