โฆ Synopsis
The maximum number of pairwise disjoint transitive triple systems (T'I'Ss) of order n is 3(n -2). Such a collection is called a large set of pairwise disjoint TI'Ss of order n. The main result in this paper is the proof of the following theorem: If n -1 or 5 (rood 6), and there exists a large set of pairwise disjoint TI'Ss of order 2 + v, then there -exists a large set of pairwise disjoint TI'Ss of order 2 + vn. Two consequences of this result are the existence of a large set of pairwise disjoint TI'Ss of every odd admissible order and the existence of a large set of pairwise disjoint TI'Ss of every admissible order ~1000, except possibly 130 and 258.

In this note, a construction of the large sets of pairwise disjoint Mendelsohn triple systems of order 72k + 6, where k > 1 and k F 1 or 2 (mod 3), is given. Let X be a set of v elements (v 2 3). A cyclic triple from X is a collection of three pairs (x, y), (y,z) and (z, x), where x,y and z are dis
