The '''wilschisma''' (monzo: {{monzo| 13 -12 1 0 0 1 }}, ratio: 532480/531441) is a 13-limit (also 2.3.5.13 subgroup) [[unnoticeable comma]] measuring about 3.38 [[cent]]s. It is the difference between the wilsorma ([[65/64]]) and the [[Pythagorean comma]], hence the name. The wilschisma can be viewed as a counterpart of the [[symbiotic comma]] – while the symbiotic comma connects 7 and 11, the wilschisma connects 5 and 13, and they differ by an [[ibnsinma]]. In addition, the wilschisma is the difference between the [[garischisma]] and the [[schismina]].
