Graph Data

I make available some of my graph data. The following tables depict graph counts related to graph connectivity (some of them now listed also in www.oeis.org). Every data file provided contains a compressed list of the first 20 MB of the smallest graphs in question (in graph6 format without graph6 header). Some data files exceed the given numbers. Since there is no standard definition of (edge-)connectivity for K0 and K1, these two graphs (n<2) are excluded.
