The 19th Revealed Initialed Chapter

The 19th revealed initialed sura was sura 43 and it is the 24th initialed sura in the compiled form of the Quran. Sura 43 has 89 verses and both the sura number and the number of verses are prime numbers with the indices of 14 and 24, respectively. The concatenation of these two indices yields 1424 and we have,

Index	Prime	Composite
1199	9721	1424

As we see the prime number 9721 and the composite number 1424 have the same index, namely 1199. Composite 1199 is a semi-prime and it is 353rd semi-prime. Recall 353 is the exponent of the 19th Gaussian Mersenne Prime and 353 is the frequency of H + M in sura 42. Note, the following table shows the permutation group of 1279. We see that the 19th and the 24th elements are 9127 and 9721. We have,

19 × 24 = 456

With index of 368 and it is the frequency H + M in sura 43.

Index	Element	Index	Element
1	1279	13	7129
2	1297	14	7192
3	1729	15	7219
4	1792	16	7291
5	1927	17	7912
6	1972	18	7921
7	2179	19	9127
8	2197	20	9172
9	2719	21	9217
10	2791	22	9271
11	2917	23	9712
12	2971	24	9721

From the above table, we see that the 19th and the 24th group elements are 9127 and 9721, respectively. The sum of these two group elements is
9127 + 9721 = 18848.

Note 18848 is the sept-prime, i.e., has 7 prime factors and it is the 473rd such sept-prime. However,

473 = 11 × 43.

And,

1143 = 9 × 127

Recall that,

4389 + 4738 = 9127
