Etymology
The name middle neutravicema is contrast to the major neutravicema, 231/230 (the difference between 11/10 and 23/21) and the minor neutravicema, 276/275 (the difference between 12/11 and 25/23). 253/252 is larger than 276/275 by 3025/3024 (lehmerisma) and smaller than 231/230 by 2646/2645 (biyativice comma). The word neutravicema was introduced by Xenllium in 2023. It is a contraction of neutral vicesimotertial comma into a single word.
