Rank Inequalities for Packing Designs and Sparse Triple Systems

- Mathematics, Computer Science
- LATIN
- 2000

Sparseness inequalities are proven to induce facets for the sparse PSTS polytope; some extremal families of PSTS known as Erdos configurations play a central role in this proof. Expand

Generalized packing designs

- Computer Science, Mathematics
- Discret. Math.
- 2013

A related class of combinatorial designs which simultaneously generalize packing designs and packing arrays is defined and methods for constructing maximum generalized packings with t = 2 and block size k = 3 or 4 are provided. Expand

Equitable colourings in the Witt designs

- Computer Science
- Australas. J Comb.
- 1997

Equitable colourings of Steiner triple systems, five Witt systems based on the Mathieu groups, and a thorough analysis of blocking sets of these designs are studied. Expand

A Technique for Constructing Symmetric Designs

- Mathematics, Computer Science
- Des. Codes Cryptogr.
- 1998

A sufficient condition is given for the matrix W⊗ M, where Mε M and W is a balanced generalized weighing matrix over G, to be the incidence matrix of a larger symmetric design. Expand

Block transitive resolutions of t-designs and room rectangles

- Mathematics
- 1997

Abstract By a resolution of t-designs we mean a partition of the trivial design ( X k ) of all k-subsets of a v-set X into t − (v′,k,λ) designs, where v′ ⩽ v. A resolution of t-designs with v = v′ is… Expand

Randomly orthogonal factorizations with constraints in bipartite networks

- Computer Science

LetDbe a (v,k,?)-difference set in a groupG. Assume thatGhas a normal subgroupNsuch thatG/Nis cyclic or nearly cyclic. Under the self-conjugacy assumption on exp(G/N), we shall give bounds on |N|… Expand

Building Symmetric Designs With Building Sets

- Mathematics, Computer Science
- Des. Codes Cryptogr.
- 1999

We introduce a uniform technique for constructing a family of symmetric designs with parameters (v(qm+1-1)/(q-1), kqm,λqm), where m is any positive integer, (v, k, λ) are parameters of an abelian… Expand

Cocyclic Orthogonal Designs and the Asymptotic Existence of Cocyclic Hadamard Matrices and Maximal Size Relative Difference Sets with Forbidden Subgroup of Size 2

- J. Comb. Theory, Ser. A
- 2001

It is proved there is a cocyclic Hadamard matrix of order 2ts for any odd integer s>1 and any t??8log2s? and there is an algebraic procedure for constructing and classifying these designs when each indeterminate is constrained to appear just once in each row and column of the orthogonal designs.
