New Constructions and Necessary Conditions for 4-GDDs With Block Size 5

t-v,k,Λ designs are well-known objects of study. Here, we define t-group divisible designs (t-GDDs) and specifically study t-GDDs, where the number of groups are less than the block size. After a short survey of t-GDDs, we will present some examples of 4-GDDs with block size 5 and two groups and pro...
