Sparse6 (.g6) Graph Format

Sparse6 file format

Description

 • Sparse6 is a text-based file format for storing one or more undirected graphs.
 • The GraphTheory[ImportGraph] and GraphTheory[ExportGraph] commands can read from and write to this format.
 • The general-purpose commands Import and Export also support this format.

Examples

Import a Sparse6 file encoding the Petersen graph.

 > $\mathrm{Petersen}≔\mathrm{Import}\left("example/petersen.s6",\mathrm{base}=\mathrm{datadir}\right)$
 ${\mathrm{Petersen}}{≔}{\mathrm{Graph 1: an undirected unweighted graph with 10 vertices and 15 edge\left(s\right)}}$ (1)
 > $\mathrm{GraphTheory}:-\mathrm{DrawGraph}\left(\mathrm{Petersen},\mathrm{style}=\mathrm{spring}\right)$
