Sets of Steiner Triple Systems of Order 9 Revisited,We determine all minimal large sets of 8 Steiner triple systems of order 9 (STS(9)); there are precisely four pairwise nonisomorphic solutions. We also classify all maximal sets of STS(9) which mutually intersect in the same number of triples (uniformly intersecting sets).

A summary is then given which considers inequivalence of Hadamard matrices of orders up to 44..The final two sections give algorithms for constructing orthogonal designs, short amicable and amicable sets for use in the Kharaghani array.
