GrayCodeSubsets[l] constructs a binary reflected Gray code on set l.

Heapify[p] builds a heap from permutation p.

HeapSort[l] performs a heap sort on the items of list l.

Josephus[n, m] generates the inverse of the permutation defined by executing every m\[Null]^th member in a circle of n members.

LNorm[p] is a value that the option WeightingFunction, used in the function SetEdgeWeights, can take. Here p can be any integer or Infinity.

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.

NextComposition[l] constructs the integer composition that follows l in a canonical order.

One is a tag used in several functions to inform the functions that only one object need be considered or only one solution be produced, as opposed to all objects or all ...

Optimum is a value that the option Algorithm can take on when used in functions VertexColoring and VertexCover.
