text: Conversely, if a median graph G contains two vertices 0 and 1 such that every other vertex lies on a shortest path between the two (equivalently, m(0,a,1) = a for all a), then we may define a distributive lattice in which a ∧ b = m(a,0,b) and a ∨ b = m(a,1,b), and G will be the graph of this lattice.
