- An animation of the LS algorithm packing a system of 100 monodisperse disks (August 18th, 2014) The Lubachevsky-Stillinger molecular dynamics algorithm is used to produce a dense packing of monodisperse disks within a squarefundamental cell with periodic boundary conditions. The dimensionless growth rate is 0.01. The initial condition was generated via RSA at a packing fraction of 0.10
- An animation of the TJ algorithm packing a system of 100 monodisperse disks (August 18th, 2014) The Torquato-Jiao (“TJ”) sphere packing protocol is used to produce a collectively-jammed packing of 100 monodisperse spheres inside a fixed square fundamental cell with periodic boundary conditions. The initial condition was generated via RSA at a packing fraction of 0.10

## Data

- Coordinates of strictly jammed MRJ packings of 2000 monodisperse spheres in three dimensions 1000-prt packinkgs as generated by the Torquato-Jiao algorithm described above (August 18th, 2014).
