Abstract :
Combining a linear programming approach with the Plotkin-Johnson argument for constant weight codes, we derive upper bounds on the size of codes of length n and minimum distance d=(n-j)/2, 0<j<n1/3 . For j=o(n1/3) these bounds practically coincide with the Tietavainen bound (1980) and are slightly better. For fixed j and j proportional to n1/3, j<n1/3-(2/9)ln n, it improves on the earlier known results
