Figure 2From: Sorting by reversals, block interchanges, tandem duplications, and deletionsSequences for elements with multiplicity = 3. An example for a sequence if an element × has a multiplicity ≥ 3. First, we remove two of the copies of x by two block interchanges and inverse tandem duplications. If this merges two components, the component can be cut by an additional reversal. For other orientations of the element x, similar sequences can be applied.Back to article page
