## Abstract Several new families of __c__βBhaskar Rao designs with block size 4 are constructed. The necessary conditions for the existence of a __c__βBRD (Ο ,4,Ξ») are that: (1)Ξ»~min~=βΞ»/3 β€ __c__ β€ Ξ» and (2a) __c__β‘Ξ» (mod 2), if Ο > 4 or (2b) __c__β‘ Ξ» (mod 4), if Ο = 4 or (2c) __c__β Ξ» β 2, if Ο =
## Abstract A group divisible design __GD__(__k__,Ξ»,__t__;__tu__) is Ξ±βresolvable if its blocks can be partitioned into classes such that each point of the design occurs in precisely Ξ± blocks in each class. The necessary conditions for the existence of such a design are Ξ»__t__(__u__βββ1)β=β__r__(__
## Abstract A resolvable modified group divisible design (RMGDD) is an MGDD whose blocks can be partitioned into parallel classes. In this article, we investigate the existence of RMGDDs with block size three and show that the necessary conditions are also sufficient with two exceptions. Β© 2005 Wil
## Abstract The object of this paper is the construction of incomplete group divisible designs (IGDDs) with block size four, groupβtype (__g, h__)^__u__^ and index unity. It is shown that the necessary conditions for the existence of such an IGDD are also sufficient with three exceptions and six po
