Examples of quasi‐random networks with perfect 4‐fold coordination bounded by identical copies of themselves can be simulated on a digital computer, starting from an arrangement of the same atoms on a lattice, and stochastically joining each atom to four of a set of its neighbors. After relaxation under a simple valence‐force law, these nets bear an encouraging resemblance to the structure of amorphous germanium. A simple calculation of the vibrational spectrum is also presented.
