SetVertexLabels[g, l] assigns the labels in l to vertices of g.
ShowGraphArray[{g_1, g_2, ...}] displays a row of graphs. ShowGraphArray[{{g_1, ...}, {g_2, ...}, \ ...}] displays a two-dimensional table of graphs.
Strings
(Combinatorica Package Symbol) Strings[l, n] constructs all possible combinatorial strings of length n from the elements of list l.
SymmetricQ[r] tests if a given square matrix r represents a symmetric relation. SymmetricQ[g] tests if the edges of a given graph represent a symmetric relation.
TransitiveClosure[g] finds the transitive closure of graph g, the supergraph of g that contains edge {x, y} if and only if there is a path from x to y.
VertexConnectivity[g] gives the minimum number of vertices whose deletion from graph g disconnects it. VertexConnectivity[g, Cut] gives a set of vertices of minimum size ...
VertexLabel is an option that can take on values True or False, allowing the user to set and display vertex labels.
Vertices[g] gives the coordinates of each vertex of graph g embedded in a plane.Vertices[g, All] gives the embedding of the graph along with graphics options associated with ...
LabelPoints is an option to DiagramPlot and PlanarGraphPlot that specifies whether to label points according to their position in the input list.
ExponentRange is an option to SetArithmetic that specifies the range of exponents that are to be allowed.
