Реферат:
A subset S of {0, 1, ..., 2t-1}^n is called a t-fold MDS code if every line in each of n base directions contains exactly t elements of S. The adjacency graph of a t-fold MDS code is not connected if and only if the characteristic function of the code is the repetition-free sum of the characteristic functions of t-fold MDS codes of smaller lengths.
In the case t = 2, the theory has the following application. The union of two disjoint (n, 4^{n-1}), 2) MDS codes in {0, 1, 2, 3}^n is a double-MDS-code. If the adjacency graph of the double-MDS-code is not connected, then the double-code can be decomposed into double-MDS-codes of smaller lengths. If the graph has more than two connected components, then the MDS codes are also decomposable. The result has an interpretation as a test for reducibility of n-quasigroups of order 4.
