Asymptotic results on the existence of 4‐RGDDs and uniform 5‐GDDs

G Ge, ACH Ling - Journal of Combinatorial Designs, 2005 - Wiley Online Library
In this paper, we continue to investigate the existence of 4‐RGDDs and uniform 5‐GDDs. It
is proved that the necessary conditions for the existence of such designs are also sufficient …

Semi-cyclic holey group divisible designs with block size three

T Feng, X Wang, Y Chang - Designs, Codes and Cryptography, 2015 - Springer
In this paper we discuss the existence problem for a semi-cyclic holey group divisible design
of type (n, m^ t)(n, mt) with block size 3 3, which is denoted by a 3 3-SCHGDD of type (n, m …

[HTML][HTML] Some more 5-GDDs, 4-frames and 4-RGDDs

H Wei, G Ge - Discrete Mathematics, 2014 - Elsevier
In this paper, we continue to investigate the existence of 5-GDDs, 4-frames and 4-RGDDs,
which have been studied by numerous researchers in the past two decades due to their vital …

The existence of four HMOLS with equal sized holes

RJR Abel, FE Bennett, G Ge - Designs, Codes and Cryptography, 2002 - Springer
In this paper, we present several new constructions for k holey mutually orthogonal Latin
squares (HMOLS) of type gn. We concentrate mainly on k= 4; here, for all but two values of …

Some new uniform frames with block size four and index one or three

G Ge, CWH Lam, ACH Ling - Journal of Combinatorial Designs, 2004 - Wiley Online Library
In this paper, some new uniform frames with block size four and index one or three are
obtained. The known existence results for (4, 1)‐frames and (4, 3)‐frames are both improved …

Semi–cyclic Holey Group Divisible Designs and Applications to Sampling Designs and Optical Orthogonal Codes

T Feng, X Wang, R Wei - Journal of Combinatorial Designs, 2016 - Wiley Online Library
We consider the existence problem for a semi‐cyclic holey group divisible design of type
with block size 3, which is denoted by a 3‐SCHGDD of type. When t is odd and or t is doubly …
