Apart from the fact that 81 has 29 verses (right of double-arrow), there's a rather interesting association between them. As shown in the Fig., there are 2489 verses from 29 to 81 (left of double-arrow). The upper two loops on the left and right show the various chps that exist between the init and un-init intermediate nodes as we traverse the paths from 29 to 81.
As we recall, 2489 is also the counts of the initials ALR in chps 10 and 11. The 10th prime is 29 and 24th prime is 89. Furthermore, 89 is the verses of chp 43, and 43 along with 52 (one of the intermediate nodes from 69 to 18 as shown) are of ord (see Glossary) 24. Meanwhile, 24 itself is of ord 13, which has 43 verses! Both 2489 and it's mirror 9842 are divisible. We recall that chp 42 is an init-chp with two sets of initials. The number of O's from the 2nd set is 98. Chp 19 has 98 verses and it also is an init-chp with initial counts of 798 = 19 × 42. This establishes a mutual symmetry between them. Both 19 and 42 are initialed with 5 letters.
There are 559 GV's between 29 and 81, where 559 = 13 × 43, relating 13 with its verses again. Also, the total norm inclusively between 29 and 81 is 817 = 19 × 43. It is noteworthy that 817 is the ALM counts of the initials in chp 31 and that the sum of the digits of the A, L, and M counts in chps 29 and 31 is 43 each. Furthermore, 2489 − 817 = 1672, which is the ALM counts in chp 29 and at the same time is the sum of the OO chps and verses from 9 to 81!
The number of GV's at the end of chp 29 is 1273 = 19 × 67, which is also the total norm at the end of chp 9. We already know that 67 is 19th prime. Additionally, chp 67 is the 19th CGV;-) Another interesting relation between 9 and 29 is as follows: From 9 to 114 there are 2948 un-init verses, signifying the 29 verses of chp 48. Also, the norm at 12:73 is 1392 = 48 × 29. Additionally, 1392 points to the fact that 13th FC is 92!
The lower recanglular loop further strengthens the relationship between 9 and 29. We notice that chps 18 and 69 are of ords 9 and 40 respectively. As the lower long arrow denotes, there are 2981 verses from 9 to 40, reaffirming the relationship between 81 and its 29 verses. The normal verses in chp 9 hint at more tie-ins with 29. We notice that 9:29 is a G2 with 128 as their sum up to that verse. The 29th GV is 9:37 which is the 719th GV from the beginning, and is also the 128th prime! The norm at 9:81 is 114, a hint at the 2948 un-init verses mentioned earlier. From 9:81 to 9:127 there are 37 GV's, which establishes a kind of symmetry with 9:29. It is also the 64th GV and 18th G2, which is interesting on its own, since, 64 has 18 verses;-)
The norm at the end of chp 29 is 1904 = 8 × 14 × 17. It's interesting that both 14 and 17 are of ord 8. The number of GV's at the end of chp 81 is 1802 = 34 × 53. Chp 53 has 62 verses, and 62 is of ord 34. Furthermore, 6234 is the total number of verses in the book (not counting the 112 tetron's). The interesting thing about 6234 is that it's the 19th permutation of 2346, which is the number of verses from 1 to 19!! And to make it even more intriguing, 2346 is the 1998th composite!!! Which points to 19 and its 98 verses;-) If we include the 112 unnumbered verses it gives a total of 6346 verses. Well, 63 is of ord 35 and 46 has 35 verses! Incidently, the init-counts of the three consecutive chps 11, 12, and 13 also add up to the same sum: 2489 + 2375 + 1482 = 6346!
If we subtract 2346 from 6234 it gives 3888 which happens to be the number of verses from 19 to 98! At the same time it relates to the fact that 38 has 88 verses too;-) Similarly, if we subtract 2489 from 6234 it gives 3745 remaining verses outside of 29 and 81. Here, we recognize 37 as the number of verses of chp 45!
Since, 2489 is also the norm at the end of chp 58, we may be able to establish a link between 29 and 58 as follows: From 29 to 58 there are 1786 verses. We immediately recognize that as a reference to chp 86 and its 17 verses. 1786 = 47 × 38, and chp 47 has 38 verses!! Chp 38 is initialed with 29 Saads. Chp 86 is of ord 57, which itself is of ord 29, plus the fact that it has 29 verses too. Chps 29 and 58 have 69 and 22 verses respectively. If we look at verse 22:69 we see the norm up to that verse is 1682. But, 1682 = 29 × 58!!!
The middle V-links in the Fig. step through nodes 69 to 52 to 49 to 18 connecting these chps with their verses. There are 18 chps and 640 verses between 52 and 69; 2489 − 640 = 1849! So, the verses spanning from 29 to 81 point to verses traversed from 69 to 52 and to the 18 verses of chp 49.
