LowerLeft is a value that options VertexNumberPosition, VertexLabelPosition, and EdgeLabelPosition can take on in ShowGraph.

LowerRight is a value that options VertexNumberPosition, VertexLabelPosition, and EdgeLabelPosition can take on in ShowGraph.

MakeSimple[g] gives the undirected graph, free of multiple edges and self-loops derived from graph g.

MaximalMatching[g] gives the list of edges associated with a maximal matching of graph g.

MaximumAntichain[g] gives a largest set of unrelated vertices in partial order g.

MaximumIndependentSet[g] finds a largest independent set of graph g.

McGeeGraph returns the unique (7, 3)-cage, a 3-regular graph with girth 7.

MinimumChainPartition[g] partitions partial-order g into a minimum number of chains.

MinimumChangePermutations[l] constructs all permutations of list l such that adjacent permutations differ by only one transposition.

MinimumVertexColoring[g] returns a minimum vertex coloring of g. MinimumVertexColoring[g, k] returns a k-coloring of g, if one exists.
