The pattern formation via clustering in a dissipative, freely cooling granular gas was studied. The clustering instability with respect to different dissipation rate and different system sizes was investigated. In the cluster-growth regime, the collision frequency showed large fluctuations because of cluster-cluster collisions and could not be predicted during cluster growth. In three-dimensional (3D), the cluster growth could be described by a power law behavior with the same critical exponents as in percolation theory.
