Theory of codes with rank distance was introduced in 1985, which can be applied to crisscross error correction and also used to build some cryptographical schemes. We know that the existence of perfect codes is an interesting topic in coding theory; as a new type of codes, we consider the existence

De Vroedt, C., On the maximum cardinality of binary constant weight codes with prescribed distance, Discrete Mathematics 97 (1991) 155-160. Let A(n, d, w) be the maximum cardinality of a binary code with length n, constant weight w (0 G w < [n/2]) and Hamming distance d. In this paper a method is di
We derive new upper bounds on the covering radius of a binary linear code as a function of its dual distance and dual-distance width . These bounds improve on the Delorme -Sole Β΄ -Stokes bounds , and in a certain interval for binary linear codes they are also better than Tieta Β¨ va Β¨ inen's bound .
