An N - n matrix on q symbols is called {w1,...,wt}-separating if for arbitrary t pairwise disjoint column sets C1,...,Ct with |Ci| = wi for 1 ≤ i ≤ t, there exists a row f such that f(C1),..., f(Ct) are also pairwise disjoint, where f(Ci) denotes the collection of components of Ci restricted to row f. Given integers N, q and w1,...,wt, denote by C(N, q, {w1,...,wt}) the maximal n such that a corresponding...
A supersaturated design is essentially a factorial design with the equal occurrence of levels property and no fully aliased factors in which the number of main effects is greater than the number of runs. It has received much recent interest because of its potential in factor screening experiments. A packing design is an important object in combinatorial design theory. In this paper, a strong link...
