The Magus comma (ratio: 50331648/48828125, monzo: [24 1 -11⟩) is a medium 5-limit comma, which is the difference between:

four classic chromatic semitones (25/24) and three classic diatonic semitones (16/15): (16/15)³/(25/24)⁴,
three lesser dieses (128/125) and a classic chromatic semitone: (128/125)³/(25/24), and
an octave-reduced stack of twelve classic major thirds (5/4) and a classic major seventh (15/8): 15/(5/4)¹².

Tempering it out leads to the Magus and Amigo temperaments.
