Ultrametric spaces bi-Lipschitz embeddable in n

It is proved that if an ultrametric space can be bi-Lipschitz embedded in n , then its Assouad dimension is less than n. Together with a result of Luukkainen and Movahedi-Lankarani, where the converse was shown, this gives a characterization in terms of Assouad dimension of the ultrametric spaces which are bi-Lipschitz embeddable in n .
