272629233/272629760 is an unnoticeable comma in the 2.3.5.13.19 subgroup. It is the amount by which the 13-comma 6656/6561 ("tetris comma") exceeds the 19/5-comma 41553/40960 (the difference between the classical major third 5/4 lowered by an apotome and the novemdecimal minor third 19/16). Their difference is small enough that sagittal accidentals do not distinguish between the 13-comma and the 19/5-comma: the most accurate possible representation of the 13th harmonic in sagittal accidentals (as three octaves above a )/||| P5) accrues this 0.0033 ¢ error.
