Group Divisible Designs with Two Associate Classes: n=2 orm=2

چکیده
In this paper we find necessary and sufficient conditions for the existence of a group divisible design GDD(n, m) of index (*1 , *2) in which n=2 or m=2, thereby completing the solution of the existence problem for all n, m, *1 , and *2 . In the process, necessary and sufficient conditions are found for the existence of an x-regular partial triple system whose complement in *Kn has a 1-factorization. 1998 Academic Press

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 کاملTwo classes of q-ary codes based on group divisible association schemes
By means of Hall's Marriage Theorem, a class of q-ary codes are obtained through block designs based on group divisible association schemes with two associate classes. If these block designs are further semiframes, another class of q-ary codes are also constructed. @ 1999 Elsevier Science B.V. All rights reserved
متن کاملSemiregular group divisible designs whose duals are semiregular
ABSTRAC"T A construction method for semiregular group divisible designs is given. This method can be applied to yield many classes of (in general, non-symmetric) semiregular group divisible designs whose duals are semiregular group divisible. In particular, the method can be used to construct many classes of transversal designs whose duals are serniregular group divisible designs, but not trans...
متن کاملVariations on the McFarland and Spence constructions of difference sets
We give two new constructions of symmetric group divisible designs using divisible difference sets. These constructions generalize the McFarland and Spence constructions of symmetric designs. Divisible designs are of interest in several parts of mathematics: The design theorist needs classes of divisible designs as "ingredients" for recursive constructions of designs. Statisticians use divisibl...
متن کاملPartial Diallel Crosses
A diallel cross is a set of all possible matings between several genotypes, which may be individuals, clones, homozygous lines, etc. Such crosses are used to estimate general and specific combining abilities of lines and crosses respectively. For ‘n’ inbreed lines, the possible F1’s are n(n–1)/2, which are to be tested in a suitably replicated randomized design. With facilities available for te...
