Abstract. We consider the possibility to embed a finite
(regular) code of a given class C
of codes in a code maximal in C
(not necessarily maximal as a code) which remains finite (regular,
respectively). A general embedding schema is proposed for the classes of
codes, which can be defined by length-increasing transitive binary
relations. As applications, positive solutions for the embedding problem
are obtained in a unified way for many classes of codes, well-known
as well as new.
