Single-track Gray codes
A.P. Hiltgen, Kenneth G. Paterson, Marco A. Brandestini · IEEE Transactions on Information Theory · 1996
A particular class of Gray codes, called single-track Gray codes, is introduced. These codes have advantages over conventional Gray codes in certain practical applications. A simple construction for single-track Gray codes is given and it is shown how to obtain such codes for a large range of parameters of practical interest.
