A note on Assmus--Mattson type theorems
Tsuyoshi Miezaki, Akihiro Munemasa, Hiroyuki Nakasora
In the present paper, we give Assmus--Mattson type theorems for codes and lattices. We show that a binary doubly even self-dual code of length 24m with minimum weight 4m provides a…

The support designs of the triply even codes of length 48
Tsuyoshi Miezaki, Hiroyuki Nakasora
In this paper, we present examples of codes all of whose weight classes support 1-designs, with duals whose classes include two that support 2-designs. We can find these examples i…
