Most graph theorists will agree that among the vast number of graphs that exist there are only a few that can be considered really interesting.
It is the aim of this House of Graphs project to find a workable definition of 'interesting' and provide a searchable database of graphs that conform to this definition. We also allow users to add additional graphs which they find interesting. In order to avoid abuse, only registered users can add new graphs.
We would also like to serve as a repository for lists of graphs (which can be downloaded in several formats) and graph generators.
These lists of graphs and generators can be found in the graph meta-directory.
