The '''berylisma''', 1874161/1874048, is an [[unnoticeable comma]] in the 2.11.37 subgroup that is the difference between a stack of four [[44/37]] thirds and an octave, which is notable because 44/37 is a continued fraction convergent to the 4th root of 2.

The name is a reference to beryllium, as this generates a 4th-octave temperament. However, the subgroup is too high-limit for me to call this beryllium.
The name is a reference to beryllium, following the tradition of naming fractional-octave temperaments after elements. However, the associated temperament with the comma is the rank-11 '''berylismic''' temperament in the 37-limit, and rank-2 '''berylic''' in the 2.11.37 subgroup. See [[4th-octave temperaments#Berylic]].
