Temperaments

Niobium comma can be regarded as the 41st-octave counterpart of Kirnberger's atom. Just as Kirnberger's atom splits the octave into 12 equal parts, and its generator is the difference between the just and 12 tone tempered fifth, niobium comma splits the octave into 41 parts, and the reduced generator is a tiny interval that stands for the difference between the most just and the 41edo-inherited fifth of temperaments supporting it.
