Comment on the paper `Inelastic granular gas: Computer simulations and kinetic theory of the cooling state' by J.M. Salazar and L. Brenig

A hierarchy of equations was introduced recently to describe the kinetics of homogeneous cooling of the gas of inelastic hard spheres. It is argued that this hierarchy does not describe this system accurately, and a simple test for this is proposed. A stochastic interpretation of the hierarchy is presented.
