The strongly minimal example is drawn directly from an innocuous-looking profinite group of odd prime exponent and nilpotence class 2. This group contains a central sugroup of prime order that is a direct factor, but all of the complements to this subgroup are dense. This example is then dressed up to give the countably categorical example, following a suggestion of E Hrushovski. This latter example also serves to refute a conjecture of M Rubin's. Unfortunately, I do not have an electronic copy of this paper, in any format.
