Background: Multinucleon transfer (MNT) processes in low-energy deep inelastic (damped) collisions of heavy ions can be employed to produce heavy neutron-enriched nuclei. Recent progress in development of radioactive-ion beam (RIB) facilities may give additional possibilities in producing nuclei with large neutron excess. Purpose: A major aim of the work is to calculate the cross sections of heavy neutron-rich isotopes with the magic number 𝑁=126 in the reactions *1*3*2 Sn + *1*9*8 Pt and &sup(136,138,140) Xe + *1*9*8 Pt within a multidimensional dynamical model based on the Langevin equations. Another purpose of the paper is to study the relative production rates of such nuclei reachable at currently working RIB facilities. Method: A multidimensional dynamical model of nucleus-nucleus collisions based on the Langevin equations [A. V. Karpov and V. V. Saiko, Phys. Rev. C 96, 024618 (2017)] has been used in the present work. This model provides a reasonable description of available experimental data. Results: Cross sections of heavy neutron-enriched nuclides obtained in the MNT reactions *1*3*2 Sn + *1*9*8 Pt and &sup(136,138,140) Xe + *1*9*8 Pt have been calculated. Relative production rates of these nuclei were estimated using beam intensities available at currently working RIB facilities. Conclusions: Using neutron-rich radioactive projectiles in multinucleon transfer reactions with the *1*9*8 Pt target, one can reach an order of magnitude higher cross sections of neutron-enriched nuclides with the magic number 𝑁=126. Relative production yields of such nuclei increase with the increasing 𝑁/𝑍 ratio of the projectile.
