Important: The networks package has been deprecated.Use the superseding command GraphTheory[Vertices] instead.

This routine returns the vertex set of G. It is normally loaded via the command with(networks) but may also be referenced using the full name networks[vertices](...).

$\mathrm{with}\left(\mathrm{networks}\right)\:$

$\mathrm{new}\left(G\right)\:$

$\mathrm{addvertex}\left(1\,2\,\mathrm{v1}\,\mathrm{v2}\,\mathrm{v3}\,a\,b\,c\,G\right)\:$

$\mathrm{vertices}\left(G\right)$

$\left\{1\,2\,a\,b\,c\,\mathrm{v1}\,\mathrm{v2}\,\mathrm{v3}\right\}$
