English Wikipedia has an article on:

15625/15552, which is sometimes called the kleisma, is the 5-limit comma that separates a stack of six classic minor thirds of 6/5 with 3/1, and is also the difference between the classic chromatic semitone (25/24) and the greater diesis (648/625). It is tempered out in Hanson temperament and the kleismic family. Like the magic comma, instead of being tempered out in 12edo, it is inflated to an entire semitone—six 6/5's make an augmented eleventh (18 steps), while 3/1 is a perfect tweltfth (19 steps); conversely, 25/24 is mapped to a semitone while 648/625 is tempered out. Its S-expression of S252 * S26 directly implies that it is expressible as (25/24)2/(27/25).
