چکیده
We give a complete solution for the existence problem of group divisible designs (or PBIBDs) with blocks of size k = 3, four groups of size (n, n, n, 1), and any two indices (λ1, λ2). Moreover, we introduce a construction of infinitely many group divisible designs with t groups of size n and one group of size 1. The construction technique utilizes our main result, together with some other known designs.

Group Divisible Designs with Two Associate Classes and with Two Unequal Groups
A group divisible design GDD(m,n; 3, λ1, λ2) is an ordered triple (V,G,B), where V is a m+ n-set of symbols, G is a partition of V into 2 sets of sizes m,n, each set being called group, and B is a collection of 3-subsets (called blocks) of V , such that each pair of symbols from the same group occurs in exactly λ1 blocks; and each pair of symbols from different groups occurs in exactly λ2 block...

متن کاملGroup divisible designs of three groups and block size five with configuration (1, 2, 2)
The subject matter for this paper is GDDs with three groups and block size five in which each block has configuration (1, 2, 2); that is, each block has exactly one point from one of the three groups and two points from each of the other two groups. We provide necessary and sufficient conditions of the existence of a GDD (n, 3, 5;λ1, λ2) with configuration (1, 2, 2). A highlight of this paper i...
متن کاملA Family of Group Divisible Designs of Block Size Four and Three Groups With l1=2 and l2=1 Using MOLS
We give a construction for a new family of Group Divisible Designs (6s+ 2, 3, 4; 1, 2) using Mutually Orthogonal Latin Squares for all positive integers s. Consequently, we have proved that the necessary conditions are sufficient for the existence of GDD’s of block size four with three groups, λ1=2 and λ2=1.

Let K = K(a, p;λ1, λ2) be the multigraph with: the number of vertices in each part equal to a; the number of parts equal to p; the number of edges joining any two vertices of the same part equal to λ1; and the number of edges joining any two vertices of different parts equal to λ2. This graph was of interest to Bose and Shimamoto in their study of group divisible designs with two associate clas...
