Etymology
The name minor semivicema is contrast to the major semivicema, 323/322, measuring about 5.37¢, which is the difference between 17/14 and 23/19. 392/391 is smaller than 323/322 by a 19-limit unnoticeable comma, 5491/5488. The word semivicema was introduced by Xenllium in 2023. It is a contraction of semi-minor vicesimotertial comma into a single word.
