The strong partially balanced t-designs can be used to construct authentication codes, whose probabilities Pr of successful deception in an optimum spoofing attack of order r for r = 0, 1, . . . , t -1, achieve their information-theoretic lower bounds. In this paper a new family of strong partially

Simple solutions of these matrix equations are easy to find; we describe ways of cortstructing rather messy ones. Our investigations are motivated by an intimate relationship between the pairs X, Y and minimal imperfect graphs.

## Abstract A Steiner pentagon system of order __v__ (SPS(__v__)) is said to be superβsimple if its underlying (__v__, 5, 2)βBIBD is superβsimple; that is, any two blocks of the BIBD intersect in at most two points. It is well known that the existence of a holey Steiner pentagon system (HSPS) of ty
In this paper, we consider explicit constructions of perfect hash families using combinatorial methods. We provide several direct constructions from combinatorial structures related to orthogonal arrays. We also simplify and generalize a recursive construction due to Atici, Magliversas, Stinson and
## Abstract In this paper we use incidence matrices of block designs and rowβcolumn designs to obtain combinatorial inequalities. We introduce the concept of nearly orthogonal Latin squares by modifying the usual definition of orthogonal Latin squares. This concept opens up interesting combinatoria
