We present a numerical study on the interplay between on-site electron-phonon (EP) interaction and inter-site Coulomb repulsion in the U/t =0.0 limit on a small cluster. Results show the formation of only S0 bipolarons. However, two polarons or bipolarons can be present at distances |i-j|=2. It is observed that inter-site Coulomb repulsion may favor formation of S0 bipolarons.
