We analyze various mechanical and network properties in the final jammed states as well as over time series of such systems to illuminate the differences between packings formed with passive and active constituents, as well as understand the underlying mechanisms of dynamical arrest in this extreme active limit. We also investigate the scaling behavior of system quantities such as the contact force distribution and pair correlation function in the jammed states, appropriately accounting for the active force.
