Abstract

We previously proposed the first nontrivial examples of a code having support tt-designs for all weights obtained from the Assmus-Mattson theorem and having support tt'-designs for some weights with some t>tt'>t. This suggests the possibility of generalizing the Assmus-Mattson theorem, which is very important in design and coding theory. In the present paper, we generalize this example as a strengthening of the Assmus-Mattson theorem along this direction. As a corollary, we provide a new characterization of the extended Golay code G24\mathcal{G}_{24}.
