Cyclic Group Divisible Designs

Calcutta Statistical Association Bulletin, 1995
New cyclic solutions of several group divisible incomplete block designs arc presented, A new group divisible desian is reported whose solution is also cyclic. We also present non-isomorphic solutions of several group divisible designs listed in the catalogue of Clatworthy (1973).

Divisible designs and groups

Geometriae Dedicata, 1992
The authors generalize previous work on translation divisible designs (with \(\lambda_ 1=0)\) and, in particular, translation transversal designs to translation divisible designs with parameters \((s,k,\lambda_ 1,\lambda_ 2)\).

Robustness group divisible designs

Communications in Statistics - Theory and Methods, 1990
Robustness of group divisible (GD) designs is investigated, when one block is lost, in terms of efficiency of the residual design. The exact evaluation of the efficiency can be made for singular GD and semi-regular GD designs as ell as regular GD designs with λ1 = 0.

Group-divisible rotatable designs

Annals of the Institute of Statistical Mathematics, 1967
By modifying the restrictions imposed on the levels of the factors in a second order rotatable design, an alternative series of response surface designs has been obtained. Thev factors of the design have been split into two groups, and the design is rotatable for each group of factors when the levels of the factors in the other group are held constant.

A generalization of group divisible t $t$‐designs

Journal of Combinatorial Designs, 2023
AbstractCameron defined the concept of generalized ‐designs, which generalized ‐designs, resolvable designs and orthogonal arrays. This paper introduces a new class of combinatorial designs which simultaneously provide a generalization of both generalized ‐designs and group divisible ‐designs.

Some new group divisible designs

Journal of Statistical Planning and Inference, 1980
Abstract The paper lists four new group divisible designs which are obtained by trial and error. These designs are believed to be new, since they are not listed in Clatworthy (1973), Freeman (1976) or John and Turner (1977).

Spreads and group divisible designs

Designs, Codes and Cryptography, 1993
This paper establishes a beautiful relation between geometric \(t\)-spreads and group divisible designs the dual of which is again a group divisible design. Let \({\mathcal S}\) be a \(t\)-spread of \(PG(d,q)\), i.e. a partition of the point set of \(PG(d,q)\) in \(t\)-dimensional subspaces, called the component of \({\mathcal S}\).
