A Steiner triple system of order u is said to be k-transrotational if it admits an automorphism consisting of a fixed point, a transposition, and k cycles of length (u-3)/k. Necessary and sufficient conditions are given for the existence of l-and 2-transrotational Steiner triple systems.

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 v v v points, in such a way that all automorphisms of U can be extended to V, for every admissible v v v satisfying v v v > gรฐuรž.
