Minimax 16-run supersaturated designs

Two-level supersaturated designs are invariably chosen using either E(s2)-optimality or the minimax criterion. Of these, E(s2)-optimality has received more interest and is the most well developed, partly because the problem seems to be more tractable. Nonetheless, minimax designs have already been found in the important cases of 8 and 12 runs. In this paper, minimax designs are derived for 16 runs for up to 60 factors.
