The 22 minimal dichotomy decompositions of the K5 K 5 -distance
In this note, we exhibit the 22 minimal dichotomy decompositions of the K5 K 5 -distance.The proof of exhaustivity is simple and relatively short. A simple checking of the solutions gives an immediate validation of two conjectures concerning the dimensionality (known result for five points) and principal component analysis (unknown result).
