Temperaments
Tempering out this comma in the 2.3.7.13.31 subgroup results in the rank-4 acronymic temperament, or in the 31-limit, the rank-8 acronymismic temperament, enabling acronymismic chords.
Etymology
The number 17576 is 26 cubed, and as there are 26 letters in the standard Latin alphabet, it is the number of distinct three-letter combinations or acronyms; the comma was named the "acronymisma" for this by Lériendil in 2025.
