Sebastien Labbe's Research code
This is a Sage optional package containing part of my own research code. It contains modules on digital geometry, combinatorics, combinatorics on words, multidimensional continued fraction algorithms, matrix cocycles, languages, substitutions, bispecial factors, double square tiles, Oldenburger sequence, Joyal bijection, Dyck word in 3D, Markov transformations, Wang tilings, 2d substitutions, polyhedron partitions, partial injections, ostrowski numeration, tikzpictures, some graphs and matrix methods.

Version 0.4.3 (August 22, 2018)
Few fixes for the publication of “Substitutive structure of Jeandel-Rao aperiodic tilings”.
Version 0.4.2 (July 20, 2018)
Few fixes for the version 2 of “A self-similar aperiodic set of 19 Wang tiles”.
Version 0.4.1 (February 9, 2018)
Few fixes for the publication of “A self-similar aperiodic set of 19 Wang tiles”. New module to solve the Magic hexagon problem.
Version 0.4 (January 20, 2018)
Version 0.4 includes new modules for Wang tilings, 2d substitutions, polyhedron partitions, partial injections, ostrowski numeration and many improvements to other modules.
Version 0.3b2 (December 11, 2016)
Version 0.3b2 includes a new module for diophantine approximations, random point generation inside polytopes, analyzing sage building time, and many improvements to previous modules.
Version 0.3b1 (June 12, 2016)
Version 0.3b1 is now a Python package available in the Python Package Index (PyPI). It was migrated from the previous sage optional spkg old-style format. It also adds code to deal with bispecial factors, some new methods of graphs, substitutions and matrices.
Version 0.2 (November 25, 2015)
Version 0.1.1 (June 3, 2015)
slabbe-0.1.1.spkg fixes a bug with gcd import error.
