In this paper, we prove the existence of a cyclic (v, 4, 1)-BIBD for v = 12t + 4, 3 t 50 using computer programs, which are useful in recursive constructions for cyclic designs....

The construction of covering arrays with the fewest rows remains a challenging problem. Most computational and recursive constructions result in extensive repetition of coverage. W...

A covering array CA(N; t, k, v) is an N ? k array such that every N ? t sub-array contains all t-tuples from v symbols at least once, where t is the strength of the array. Coverin...

Let k, v, t be integers such that k v t 2. A perfect hash family PHF(N; k, v, t) can be defined as an N ? k array with entries from a set of v symbols such that every N ?t suba...
