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

## Abstract A Steiner pentagon system of order __v__ (SPS(__v__)) is said to be super‐simple if its underlying (__v__, 5, 2)‐BIBD is super‐simple; 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 row–column 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
