We would also like to serve as a repository for lists of graphs (which can be downloaded in several formats) and graph generators.

Currently we provide only a small selection. Some lists are hosted on our website, while others are direct links to pages hosted by other people. In the latter case the name of the host is listed between brackets. Some of the pages of interesting graph classes also contain links to generators which can be used to generate these graphs.

If you have other complete lists of graphs which you would like to see added to the House of Graphs, don't hesitate to contact us at jan.goedgebeur[at]ugent.be.
