A Steiner triple system of order u is called reverse if its automorphism group contains an involution fixing only one point. We show mat such a system exists if and only if u = 1,3, 9 or 19 (mod 24).

## 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 __v__ββ‘β1 (mod 6). The other construction is the Wilson construction that we specify to give a nonβresolvable
## Abstract Lindner's conjecture that any partial Steiner triple system of order __u__ can be embedded in a Steiner triple system of order __v__ if $v\equiv 1,3 \; ({\rm mod}\; 6)$ and $v\geq 2u+1$ is proved. Β© 2008 Wiley Periodicals, Inc. J Combin Designs 17: 63β89, 2009
