Scaling of the translational center-of-mass diffusion coefficient Dtr of spherical multi-bead particles with the number of beads, N. Without HI the usual N-1 scaling was obtained whereas with HI the scaling was close to the N-1/3 scaling for a single sphere when the volume is proportional to the number of beads. The open squares denote results from simulations without HI in which the single bead diffusion coefficient was rescaled for each particle size (= bead number N) individually in order to reproduce the scaling of Dtr with HI.
