Abstract : It is often desirable to use Gray codes with properties different from those of the standard binary reflected code. Previously, only short codes (32- to 256-element) could be systematically generated or found with a given set of properties. This report describes a technique where long codes (65,000-element or longer) as well as short codes can be systematically generated with desired properties. The technique is described and demonstrated by generating codes of various lengths with the desired property of equal column change counts.
