Constructions are given for the production of symmetric block designs whose point set is divisible (partitionable) in several ways. Some properties of the dual design are also considered. © 2006 Wiley Periodicals, Inc. J Combin Designs 14: 415–422

We are already familiar with (υ, k, λ)-difference sets and (υ, k, λ)-designs. In this paper, we will introduce a new class of difference sets and designs: (υ, k, [λ1, λ2, … , λm])-difference sets and (υ, k, [λ1,λ2, … , λm])-designs. W

Hilbert and Cohn-Vossen once declared that the configurations of Desargues and Pappus are by far the most important projective configurations. These two are very similar in many respects: both are regular and self-dual, both could be constructed with

Let k, λ, and υ be positive integers. A perfect cyclic design in the class PD(υ, k, λ) consists of a pair (Q, B) where Q is a set with |Q| = υ and B is a collection of cyclically ordered k-subsets of Q such that every ordered pair of elements of

In this paper we investigate the spectrum of a variety of quasigroups satisfying the 2-variable identity x(xy) = yx, called Stein quasigroups. Stein quasigroups are known to be self-orthogonal and have been given a considerable amount of attention be
