N2 - We study the class of codes defined by the row space of the minimum distance relation matrix of t th and l th layers of Hamming graph H(m,q). By concatenating such matrices we obtain many distance-optimal codes of length up to 128. For arbitrary q,t,n,k we prove an analogue of a well-known Wilson rank formula [12] and find the dimensions of the codes in this class. For t=l−1, the codes are locally recoverable and include the codes from work of [11] for q=2. We show that the codes with q=2 are optimal locally-recoverable codes in our class.
