A method is disclosed for efficient multiplexing of a plurality of electrodes in a nerve stimulator using improved, predetermined, regular, repeatable geometric patterns arranged in a predetermined mosaic to form a desired array. Multiple electrodes within said array are addressed by the nerve stimulator as being a stimulating electrode by an instruction specifying a single identifier, indicating a position within each regular geometric pattern. As such, each electrode within the array, maintaining the specified position within its respective repeatable geometric pattern, becomes a stimulating electrode and is connected to the appropriate electronic circuit for subsequent, potential use in nerve stimulation.
