Abstract
We characterize Polish ultrametric spaces all of whose isometric embeddings into the Polish ultrametric Urysohn space with the same set of distances are extensive, that is, they give rise to an embedding of their respective isometry groups. This generalizes a result proved by Gao and Shao (2011) [2].
