It is shown that if a nontrivial perfect mixed e-code in Q, x Q2 x . . . x Q, exists, where the Qi are alphabets of size qi, then the qt, e and n satisfy certain divisibility conditions.
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
