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
