Abstract
A (K4 - e)-design on v + w points embeds a Steiner triple system (STS) if there is a subset of v points on which the graphs of the design induce the blocks of a STS. It is established that w ≥ v / 3, and that when equality is met that such a minimum embedding of an STS (v) exists, except when v = 15.
