It is shown that there is a function g on the natural numbers such that a partial Steiner triple system U on u points can be embedded in a Steiner triple system V on ν points, in such a way that all automorphisms of U can be extended to V , for every admissible ν satisfying ν > g ( u ). We find exponential upper and lower bounds for g . © 2005 Wiley Periodicals, Inc. J Combin Designs.
