        <p>V-Phenylenic nanotubes VPNTU[l,k] and nanotori VPNTO[l,k] are theoretically predicted carbon-based nanostructures with promising electronic and mechanical properties. While experimental synthesis remains elusive, computational studies suggest they could exhibit exceptional conductivity, strength, and potential applications in electronic and materials science. In this article, the new Revan indices (RI) for molecular graph (MG), line graph (LG) and subdivision graph (SG) of VPNTU [l, k] and VPNTO [l, k] are investigated. By utilizing M-polynomial obtained from MG, LG and SG and MATLAB software coding, calculations and results obtained from research are presented.</p>
