The arrangement of the surahs prefixed with huruf muqatta'at within the Quranic text.
The horizontal graduated line represents the respective lengths of the 114 Quran surahs.
The three surahs 7, 19 and 38, prefixed respectively with (Alif Lam Mim Sad), (Kaf Ha Ya Ayn Sad) and (Sad), mark the subdivision of the Quranic text into approximately 4 quarters. Each quarter contains a group of surahs prefixed with the same (repeated) combination of letters. Each group of repeated combination has a single unique combination (in green) except group 1 which is composed with only 2 (Alif Lam Mim).
