(Note that the [Open Problem Garden website](http://www.openproblemgarden.org/) only lists statements and some recent references that are usually not of a computational flavor. The idea is to avoid wasting time repeating an ultimately unsuccessful approach.).

A centralised website for computational attempts in graph theory and metric geometry?
There are a few websites with lists and/or databases of graphs, maps and polytopes.


* [House of graphs](https://hog.grinvin.org) has a searchable database of interesting graphs and aims to serve as a repository for lists of graphs and graph generators,
* [Encyclopedia of graphs](http://atlas.gregas.eu) is an online encyclopedia of graph collections with some data about different families of graphs,
* [Database of graphs in combinatorica format](http://www3.cs.stonybrook.edu/~skiena/combinatorica/graphs/),
* [Encyclopedia of Finite Graphs](https://github.com/thoppe/Encyclopedia-of-Finite-Graphs) is a "set of tools and data to compute all known invariants for simple connected graphs".


There are several censuses of symmetric objects (for example [Marston Conder](https://www.math.auckland.ac.nz/~conder/), [Dimitri Leemans](https://www.math.auckland.ac.nz/~dleemans/resources.html), [Primož Potočnik](http://www.fmf.uni-lj.si/~potocnik/work.htm)).


I would also like to know about other websites of similar nature out there, since I'm working on one myself. It's still an early stage [project](http://www.discretezoo.xyz), but has some use already. It aims to one day be able to provide a platform for computational attempts for all sorts of discrete objects (you can see some features for the exploratory aspect on the website).
