This site is dedicated to objects in discrete geometry and their abstraction in terms of oriented matroids.

Use the navigation bar on the top of this page or the following links to access

• catalogs of oriented matroids, point configurations, and hyperplane arrangements;
• some software for computations with oriented matroids (upcoming);
• references and bibliography (at the moment, an online glossary and a bibtex file);
• a list of people who are interested in oriented matroids and related structures.

This site is under construction. We invite you to contribute in whatever form you like. Please send any material, suggestions, or corrections to the maintainer of this site (see bottom of this page).

Best regards

Lukas Finschi
