ToCanonicalSetPartition

ToCanonicalSetPartition[sp,set]

reorders sp into a canonical order with respect to set.

ToCanonicalSetPartition[sp]

reorders sp into canonical order, assuming that the Wolfram Language knows the underlying order on the set for which sp is a set partition.

Details and Options

  • To use ToCanonicalSetPartition, you first need to load the Combinatorica Package using Needs["Combinatorica`"].
  • In the canonical order, the elements of each subset of the set partition are ordered as they appear in set, and the subsets themselves are ordered by their first elements.
