In this paper, we introduce a new concept -- overlarge sets of generalized Kirkman systems (OLGKS), research the relation between it and OLKTS, and obtain some new results for OLKTS. The main conclusion is: If ther...
Kirkman holey covering designs (KHCD)are a class of important designs which can be used to cryptography. So the existence of KHCD has attracted many researchers'attention(see[1,2,3] for example).
A supersaturated design is essentially a factorial design with the equal occurrence of levels property and no fully aliased factors in which the number of main effects is greater than the number of runs. It has receiv...
