Abstract
A model, consisting of triangular trimers on the triangular lattice is pres ented. In analogy to the dimer problem, these particles cover the lattice c ompletely without overlap. The model has a honeycomb structure of hexagonal cells separated by rigid domain walls. The transfer matrix call be diagona lized by a Bethe Ansatz with two types of particles. This leads to an exact expression for the entropy on a two-dimensional subset of the parameter sp ace.
