Abstract:
If S is a transitive metric space, then |C|\cdot|A| \le |S| for any distance-$d code C and a set A, ``anticode'', of diameter less than d. For every Steiner S(t,k,n) system S, we show the existence of a q-ary constant-weight code C of length~n, weight~k (or n-k), and distance d=2k-t+1 (respectively, d=n-t+1) and an anticode A of diameter d-1 such that the pair (C,A) attains the code--anticode bound and the supports of the codewords of C are the blocks of S (respectively, the complements of the blocks of S). We study the problem of estimating the minimum value of q for which such a code exists, and find that minimum for small values of t.
