Expand description
Static atlas-of-graphs data tables (ALGO-CN-021).
Transliterated byte-for-byte from
references/igraph/src/constructors/atlas-edges.h — the flat-encoded
edge list for the 1253 simple unlabelled undirected graphs on
0..7 vertices in the Read-Wilson “An Atlas of Graphs” (1998)
ordering (vcount asc, ecount asc, degree sequence lex asc,
automorphism count asc within each cell).
ATLAS_EDGES holds [vcount, ecount, edge0_a, edge0_b, …] rows
packed end-to-end. ATLAS_EDGES_POS[i] is the starting offset of
graph i in ATLAS_EDGES. ATLAS_EDGES_POS.len() == 1253.
