2646/2645, the biyativicema or biyativice comma is a 23-limit superparticular comma of about 0.65 cents. It forms the difference between two 23/21s and 6/5, and between two 28/23s and 40/27. By tempering it out is defined the biyativice temperament, which enables the biyativice chords.

Etymology

The word biyativice is introduced by Xenllium in 2023. It is a contraction of biyatisma (121/120, the difference between 11/10 and 12/11) and vicesimotertial (23-limit) into a single word.
