Query: Tegula -- exploring a galaxy of two-dimensional periodic tilings   Periodic tilings play a role in the decorative arts, in construction and in
crystal structures. Combinatorial tiling theory allows the systematic
generation, visualization and exploration of such tilings of the plane, sphere
and hyperbolic plane, using advanced algorithms and software.Here we present a
"galaxy" of tilings that consists of the set of all 2.4 billion different types
of periodic tilings that have Dress complexity up to 24. We make these
available in a database and provide a new program called Tegula that can be
used to search and visualize such tilings.
  Availability: All tilings and software and are open source and available
here: https://ab.inf.uni-tuebingen.de/software/tegula.
