+The '''immunity comma''' ({{monzo|legend=1| 16 -13 2 }}, [[ratio]]: 1638400/1594323) is a [[Medium comma|medium]] [[5-limit]] [[comma]] of about 47.2 [[cent]]s. It is the difference between the [[256/243|Pythagorean diatonic semitone (256/243)]] and a stack of two [[syntonic comma]]s, or between a [[25/24|diptolemaic chromatic semitone (25/24)]] and a [[Pythagorean comma]].
