"Configurations of points modulo translation"

The moduli space of stable nodal scaled marked lines constructed by Ziltener and Mau-Woodward is a compactification of the set of configurations of n distinct points on a line modulo translation. I will discuss a similar moduli space (in which the points are allowed to coincide) and some properties of it: it is equivariant, it represents a natural moduli functor, it is a degeneration of the Losev-Manin space, and it admits a small resolution by the augmented wonderful variety associated to the graphic matroid of a complete graph.
