Classification of six-point metrics
The electronic journal of combinatorics, Tome 11 (2004) no. 1
There are $339$ combinatorial types of generic metrics on six points. They correspond to the $339$ regular triangulations of the second hypersimplex $\Delta(6,2)$, which also has $14$ non-regular triangulations.
