The punctisma, with a ratio of 43904/43875, is the difference between three 15/14 semitones and a 16/13 neutral third. Its tempering out is characteristic of the 10n family of edos, which approximate both of these intervals within a fraction of a cent. Surprisingly, it is also tempered out in 159edo, 171edo, and 311edo. It was named by Jerdle and Aura from Latin pūnctum ("point") based on both its relation to the 10n family of EDOs as well as its small size.
