Abstract

We have constructed all 5450 combinatorially possible vertex configurations formed by the Ammann rhombohedra. The defectiveness of the vertex configurations is quantified by a penalty functional defined as the minimal sum of squared distances between the dual acceptance domains for the constituent tiles of a given vertex. The vertices are then classified as ideal versus defective, quasiregular versus strictly forbidden, and regular versus singular. The classification is refined by defining rank as the dimension of the dual overlap and degree as the highest dimension of a facet violating the conditions of regularity.
