graph6
format is a somewhat common encoding for graphs, and is available in several graph libraries/mathematical software, including NetworkX.
I’m currently working on a project that would benefit from moving to Julia and if there was a graph package with support for this format it would make it a lot easier to port it over.
The package LightGraphs.jl has support for quite a few formats already, so I thought about maybe making a feature request there but decided to ask around first.
For anyone curious, here is a description of the format.
