We present a complete list of all combinatorial types of generic Kantorovich-Rubinstein-Wasserstein (KRW) polytopes associated with metric spaces on up to 6 points that are generic in the sense of Gordon and Petrov, see [1]. These polytopes and their properties are described in detail in [2]. The catalog of KRW polytopes was computed using certain regular triangulations of the full root polytope, see Section 4 in [2]. These regular triangulations were enumerated up to symmetry by Jrg Rambau using the new topcom package described in [3]. The provided data comes in three parts. The files ending in ".result" contain the originaltopcom output including the specific regular triangulations of the root polytope. There are julia files that contain these triangulations ("triangulations_x.jl"), one triangulation per line. There is anOSCAR script ("read_triangulations.jl") that reads these triangulations and produces sample metrics associated with each of these triangulations. References: [1] J. Gordon and F.
