Let RB(3, \*; v) denote a resolvable \*-fold triple system of order v. It is proved in this paper that the necessary and sufficient conditions for the embedding of an RB(3, \*; v) in an RB(3, \*; u) are u 3v and (i) u#v#3 (mod 6) if \*#1 (mod 2), (ii) u#v#3 (mod 3) if \*#0 (mod 4), or (iii) u#v#0 (m

An HMTS of type {n1 , n2 , . . . , n h } is a directed graph DKn 1 ,n 2 ,...,n h , which can be decomposed into 3-circuits. If the 3-circuits can be partitioned into parallel classes, then the HMTS is called an RHMTS. In this article it is shown that the RHMTSs of type m h exist when mh โก 0 (mod 3)
A cyclic triple (a, b, c) is defined to be set { (a, b) ,(b,c),(c,a)} of ordered pairs. A Mendelsohn triple system of order v, M(2,3, u), is a pair (M, fi), w h ere M is a set of u points and fi is a collection of cyclic triples of pairwise distinct points of M such that any ordered pair of distinct
