Quran How many Interchangeable Pauses?

[John Muslim]

An 'interchangeable pause', where two marks are found each consisting of three dots. A reciter may pause on either of them but not on both. As in 2:2 (Surah Al Baqarah) where 2 different meanings can be derived depending where you pause. Does any one know how many there are and where? I've found four instances so far 2:2, 5:26, 7:171 and 14:9.
