i. Ring primitive. The ring table is topologically linked
to the face table and edge table within a coverage.
j. Ring table. The ring table contains a ring row
identifier column, face column, and edge column. The
first entry in the ring table for a particular face
contains the outer ring of that face. Subsequent rings
for the same face indicate internal rings within the
outer ring. The format and an example of the content
for a ring primitive table are shown in TABLE 57.
