Verse-Ascension symmetry
The top and bottom pairs of parallel, horizontal arrows sketch out the duality involved among the selected chapters in regard to verses and ascensions (see Glossary). In the top arrows, the 1122 verse span from 11 to 21 stands in sharp contrast to 1121 ascension span from 11 to 22! The latter also form an ord pair. Likewise, in the bottom arrows, we observe two pairs of chapters and their spans, reciprocally, split and rejoin to recreate each other: the verse span from 25 to 76 is 2767 and the ascension span from 27 to 67 is 2576!
The cept span from 11 to 25 (left vertical dotted arrow) is 19 × 65, where, the factor 65 is of ascension 25 (dotted curved S-arrow). The three corners 21, 25 and 67 interconnect via the central intermediary 77 through cept, verse and ascension, respectively (the three curved dotted arrows). The right dotted vertical C-arrow underlines 22 and 76 as a cept pair.
