Try 4,2,2: sorted positions with duplicates removed

Use the four-page mapping-four.pdf: 1=COVER, 2=CONTENTS, 3=BODY-1, 4=BODY-2. This specimen tests selection syntax independently of the earlier six-page illustration.

1. Import it and enter 4,2,2 using ordinary commas in the extraction field.

2. Download, reopen and record both page markers and the physical count.

3. Run a separate comparison with 4-2: endpoints are normalized to positions 2 through 4, not played backward.

4,2,2 should yield CONTENTS then BODY-2: physical positions 2 and 4, with only one copy of 2. The range 4-2 should yield CONTENTS, BODY-1, BODY-2.

If the requirement is BODY-2 first with two copies of the contents page, this selection field does not fulfill it. Extract, then use a page editor supporting reordering and duplication, and verify the entire resulting sequence.
