Relaxation properties in a diffusive model of extended objects on a triangular lattice

► We study the relaxation properties in a 2D lattice gas model. ► Shapes are made by self-avoiding random walks on a triangular lattice. ► Suppression of rotational motion results in a subdiffusive dynamics. ► Percolation threshold of compact shapes exceeds the threshold of elongated ones. ► Critical density for some shapes is below the jamming limit.
