Return the list [G0,G1,...,G1252] of graphs as named in the Graph Atlas.
G0,G1,...,G1252 are all graphs with up to 7 nodes.
- The graphs are listed:
- in increasing order of number of nodes;
- for a fixed number of nodes,
in increasing order of the number of edges;
- for fixed numbers of nodes and edges,
in increasing order of the degree sequence,
for example 111223 < 112222;
- for fixed degree sequence, in increasing number of automorphisms.
Note that indexing is set up so that for
GAG=graph_atlas_g(), then
G123=GAG[123] and G[0]=empty_graph(0)
