Group Divisible Design (n1, n2, n3,4; λ1, λ2), for n1 = 3,n2 = n and n3 = n + 1

Namyalo, Kasifa (IOSR Journal of Mathematics (IOSR-JM), 2021)

The work in this article is about Group Divisible Designs (GDDs) with three groups of sizes n1, n2 and n3, where n1=3, n2=n and n3=n+1 and block size four. First, we establish necessary conditions for the existence of ...
