Tegula is a program for displaying and exploring two-dimensional periodic tilings, based on the concept of Delaney-Dress symbols. Tegula was written by Daniel Huson and Rüdiger Zeller, using code by Klaus Westphal. Tegula is written in Java (12) and uses JavaFX.

We provide three databases of tilings, containing all periodic tilings with Dress complexity ≤ 18 and all euclidean and spherical tilings with Dress complexity ≤ 24. These were computed using genDSyms, available here: https://github.com/odf/julia-dsymbols.
We have computed 2.4 billion tilings in total, but that file is too big to put online.
The underlying mathematics, algorithms and sofware are described in this paper:
