NormalizeVertices[v] gives a list of vertices with a similar embedding as v but with the coordinates of all points scaled to be between 0 and 1.

NoSelfLoops is an option value for Type.

NthPair[n] returns the n\[Null]^th unordered pair of distinct positive integers, when sequenced to minimize the size of the larger integer. Pairs that have the same larger ...

NthSubset[n, l] gives the n\[Null]^th subset of list l in canonical order.

NumberOf2Paths[g, v] returns a sorted list that contains the number of paths of length 2 to different vertices of g from v.

NumberOfCompositions[n, k] counts the number of distinct compositions of integer n into k parts.

NumberOfDerangements[n] counts the derangements on n elements, that is, the permutations without any fixed points.
