Basic #

Vertices of a path, in first-appearance order

live ↗

In$\mathrm{VertexList}(\mathrm{Graph}(\bigl\lbrack\mathrm{UndirectedEdge}(3, 1), \mathrm{UndirectedEdge}(1, 2)\bigr\rbrack))$Out$\bigl\lbrack3, 1, 2\bigr\rbrack$

Properties #

A single-vertex graph has one vertex

live ↗

In$\mathrm{Length}(\mathrm{VertexList}(g))$Out$1$

A label that isn't among the vertices is not found, so the position list is empty

live ↗

In$\mathrm{Position}(\mathrm{VertexList}(g), \text{c})$Out$\bigl\lbrack\bigr\rbrack$
