Abstract
Given a countable group , we say that a metrizable flow is model-universal if by considering the various invariant measures on , we can recover every free measure-preserving -system up to isomorphism. Weiss has constructed a minimal model-universal flow. In this note, we provide a new, streamlined construction, allowing us to show that a minimal model-universal flow is far from unique.
