It will take about 1 week, at most 2 weeks. The number of graphs
is something like 550 million. Don't try storing them all unless
you have about 35GB free.
If your application imposes some restrictions on the graphs such as
a subgraph that is forbidden, it might be possible to make the
generation a lot faster with fewer useless outputs.
