When Do Subset Sums in Finite Abelian Groups Support $2$ -Designs?

Hengfeng Liu, Chunming Tang, Cuiling Fan +1

Subset sums over finite abelian groups lie at the intersection of additive combinatorics, design theory, and coding theory. Let $G$ be a finite abelian group, and let $\cB_k^x$ be…

Combinatorial $t$ -Designs from Finite Abelian Groups and Their Applications to Elliptic Curve Codes

Hengfeng Liu, Chunming Tang, Cuiling Fan +1

In this paper, we establish the conditions for some finite abelian groups and the family all the $k$ -sets in each of them summing up to an element $x$ to form $t$ -designs. We fully…
