Theisometric Ramsey numberof a familyof digraphs is the smallest number of vertices in a graphsuch that any orientation of the edges ofcontains every member ofin the distance‐preserving way. We observe that the isometric Ramsey number of a finite family of finite acyclic digraphs is always finite, and present some bounds in special cases. For example, we show that the isometric Ramsey number of the family of all oriented trees withvertices is at most.
