For a given number of nodes how many non-isomorphic graphs are available? Might be this is an open problem. For less number of vertices some computational statistics available. 


I want to get all non-isomorphic graphs of order $5, 6, \dots 12$. Is there any complete list of all non isomorphic graphs available for a given number of nodes? If possible please give me its links or some references.


If I wish to calculate it myself, which software package may be useful?



How to generate computational data in graph theory?
Use Brendan McKay's program geng, which is distributed with the nauty/Traces package and is available from <http://pallini.di.uniroma1.it/>.


There are about 165091172592 graphs on 12 vertices, so it might take you a while.
