Garden of Eden (GoE) is the nickname of an irreproducible state, which can appear only as an initial configuration, and not as a result of time evolution. Here we investigate GoEs in systems of bistable nanoscopic wires, which interact magnetostatically. The wires are randomly distributed on a square lattice, with their directions parallel (Nx wires) or perpendicular (Ny=N-Nx wires) to the applied magnetic field. The results are presented on the statistics of GoEs, as dependent on Nx. As a rule, most GoEs appear when Nx is close to Ny. Also, most GoEs include many wires parallel to the field and/or a few wires perpendicular to the field. The results can be useful for modelling safety devices.
