The $n$th symmetric product of a metric space is the set of its nonempty subsets with cardinality at most $n$, equipped with the Hausdorff metric. We prove that every symmetric product of the line is an absolute Lipschitz retract and admits a bi-Lipschitz embedding into a Euclidean space of sufficiently high dimension.
