On the degree pairs of a graph
Yu-pei Huang, Chia-an Liu, Chih-wen Weng
Let G be a simple graph without isolated vertices. For a vertex i in G, the degree d_i is the number of vertices adjacent to i and the average 2-degree m_i is the mean of the degre…

A family of group divisible designs with arbitrary block sizes
Yu-pei Huang, Chia-an Liu, Yaotsu Chang +1
Recently, a construction of group divisible designs (GDDs) derived from the decoding of quadratic residue (QR) codes was given. In this paper, we extend the idea to obtain a new fa…
