A Pair of Disjoint 3-GDDs of type g^t u^1

Yanxun Chang, Yeow Meng Chee, Junling Zhou

Pairwise disjoint 3-GDDs can be used to construct some optimal constant-weight codes. We study the existence of a pair of disjoint 3-GDDs of type $g^{t} u^{1}$ and establish that its n…

Decompositions of 3-uniform hypergraph K_v^{(3)} into hypergraph K_4^{(3)}+e

Tao Feng, Yanxun Chang

In this paper it is established that a decomposition of a 3-uniform hypergraph K_v^{(3)} into a special kind of hypergraph K_4^{(3)}+e exists if and only if v\equiv 0,1,2 (mod 5) a…
