The support designs of the triply even codes of length 48
Tsuyoshi Miezaki, Hiroyuki Nakasora · arXiv (Cornell University) · 2018
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 in the triply even binary codes of length 48, which have been classified by Betsumiya and Munemasa.
