Candelabra systems and designs
H Mohácsy, DK Ray-Chaudhuri - Journal of statistical planning and …, 2002 - Elsevier
Combinatorial structures called candelabra systems can be used in recursive constructions
to build Steiner 3-designs. We introduce a new closure operation on natural numbers …

[HTML][HTML] Group divisible designs with block size four and group type gum1 for small g
In this paper, we continue to investigate the spectrum for {4}-GDDs of type gum1 with small
g. We show that, for each g∈{2, 4, 5, 12, 15} and each admissible pair (u, m), a {4}-GDD of …

On Group-Divisible Designs with Block Size Four and Group-Type g u m 1
G Ge, RS Rees - Designs, Codes and Cryptography, 2002 - Springer
We investigate the spectrum for {4}-GDDs of type gum 1. Wedetermine, for each even g, all
values of m for which a {4}-GDD of type gum 1 exists, for every 'fourth'value of u. We …
