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

Abstract
We consider two wellβknown constructions for Steiner triple systems. The first construction is recursive and uses an STS(v) to produce a nonβresolvable STS(2__v__β+β1), for vββ‘β1 (mod 6). The other construction is the Wilson construction that we specify to give a nonβresolvable STS(v), for vββ‘β3 (mod 6), vβ>β9. Β© 2004 Wiley Periodicals, Inc. J Combin Designs 13: 16β24, 2005.

## Abstract Let __SS__~__R__~(__v__, 3) denote the set of all integer __b__\* such that there exists a __RTS__(__v__, 3) with __b__\* distinct triples. In this paper, we determine the set __SS__~__R__~(__v__, 3) for __v__ β‘ 3 (mod 6) and __v__ β₯ 3 with only five undecided cases. We establish that _
An MTS(v) [or DTS(v)] is said to be resolvable, denoted by RMTS(v) [or RDTS(v)], if its block set can be partitioned into parallel classes. An MTS(v) [or DTS(v)] is said to be almost resolvable, denoted by ARMTS(v) [or ARDTS(v)], if its bloak set can be partitioned into almost parallel classes. The
A Steiner triple system of order n (STS(n)) is said to be embeddable in an orientable surface if there is an orientable embedding of the complete graph Kn whose faces can be properly 2-colored (say, black and white) in such a way that all black faces are triangles and these are precisely the blocks
The code over a finite field F, of a design D is the space spanned by the incidence vectors of the blocks. It is shown here that if D is a Steiner triple system on v points, and if the integer then the ternary code C of contains a subcode that can be shortened to the ternary generalized Reed-Muller
## Abstract In this paper, we present a conjecture that is a common generalization of the DoyenβWilson Theorem and Lindner and Rosa's intersection theorem for Steiner triple systems. Given __u__, __v__ β‘ 1,3 (mod 6), __u__ < __v__ < 2__u__β+β 1, we ask for the minimum __r__ such that there exists a
