Generation of Matroids

This page presents an application of the paper:
Mohamed Barakat, Reimer Behrends, Christoper Jefferson, Lukas Kühne, and Martin Leuner: On the generation of rank 3 simple matroids with an application to Terao’ freeness conjecture

The main contribution of this article is a large scale generation of a certain class of matroids in HPC-GAP. Subsequently, we stored these matroids in a publicly availabel Arango DB database: https://matroid.mathematik.uni-siegen.de. This enabled us to answer the following question:

The code is presented as a Jupyter notebook based on the Julia package CapAndHomalg. It can be downloaded here: MatroidGeneration.ipynb.

You can run the notebook online by clicking the binder badge below.
