Huruf Muqatt'at (حروف مقطعات‎) part-2

Continuing from part-1, I would like to present some of the interesting findings regarding the Huruf al Muqatt'at in the Quran. Allah knows the best.

Broadly looking at these huruf; it appears that the number 7 is consistently ingrained in them with some harmony. Here are some examples based on the numbers. When I say 'divisible by 7' below, it is implied that it is 'divisible by 7 without a remainder'.

1) Total number of unique combinations of the Huruf al Muqatt'at in the Quran is 14 - divisible by 7 (Fig.1)

2) Total number of unique individual Arabic Huruf (letters) used is 14 - divisible by 7. (Fig.2)

3) Unique number of occurrences of the combinations of huruf are 1, 2, 5, 6 and 7 times - adding to 21 - divisible by 7. (Fig.3)

4) There 19 Surahs in which the Huruf al Muqatt'at appear as separate verses. For example Surah Al Baqrah (Chapter 2) verse 1 only has الم  . There are 19 such Surahs in the Quran. If we add each Surah number to its total verses, we get a sum (we call it Sum X). There are 19 such Sum X available to us.
Out of which, 7 are even Sum Xs, and 12 are odd. There are some interesting facts about these Sum Xs
         4.1) Adding the 7 even Sum Xs - we get 868 - divisible by 7 (and 14 and 28). (Fig.4)
         4.2) Adding the 12 odd Sum Xs - we get 1624 - divisible by 7 (and 14 and 28). (Fig.5)
         4.3) Adding all 19 odd Sum Xs - we get 2492 - of course divisible by 7 (and 14 and 28). (Fig. 6)
