Tempering out this comma not only equates 25/24 with 26/25 – splitting 13/12 in half and going part of the way towards splitting the 9/8 whole tone into three (the other comma that needs to be tempered in order to finish this job is 676/675) – but also equates 39/32 with the interval that results from stacking four 5/4 major thirds then octave-reducing.
