The family of t-designs - part II

This is a continuation of Part I of our previous paper (1980) on conbinatorial aspects of t-designs with t ≥ 2. Along the same developments as in Part I, this paper provides tables, assorted examples of t-designs, and interesting unsolved problems. A brief background and a short review of the literature related to each unsolved problem is also provided. Some tables list parameters of designs whose existence or nonexistence is not established in literature. Notation and numbering of Part I are still used here.
