The '''tridecapyth comma''' is the [[13-limit]] [[unnoticeable comma]] '''3489660928/3486784401''', which measures roughly 1.43 [[cent]]s. It is the interval which, when tempered out, not only equates [[13/8]] with a stack of twenty [[3/2]] perfect fifths octave-reduced, and, consequently, a stack of four [[256/243]] Pythagorean limmas with [[16/13]], but also a stack of two [[Pythagorean comma]]s with the [[1053/1024]] tridecimal quartertone. | The '''tridecapyth comma''' is the [[13-limit]] [[unnoticeable comma]] '''3489660928/3486784401''', which measures roughly 1.43 [[cent]]s.
