Etymology

The name major neutravicema is contrast to the middle neutravicema, 253/252 (the difference between 12/11 and 23/21) and the minor neutravicema, 276/275 (the difference between 12/11 and 25/23). 231/230 is larger than 253/252 by a 23-limit unnoticeable comma, 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.
