How Antichain connects Entity context

The extracted context around Antichain shows recurring relationship patterns in the source. For example, Antichain → antichain that has cardinality at least as large as every other antichain, antichain that is not a proper subset of any other antichain, subset of a partially ordered set such that any two distinct elements in the subset are incomparable.The size of the largest antichain in a finite partially ordered set is known… Another extracted example is Antichain → Dilworth's, Mirsky's, Similarly. Use these groups to spot repeated connection types before inspecting the individual relationships.
