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
## Abstract The temperature dependence of the concentration and shape of long dislocation lines in pure, nearly perfect gallium crystals has been measured by Xβray topography in anomalous transmission (Borrmannβtopography). The dislocation structure did not change appreciably between temperatures o
