456/455, the abnobisma, is a 19-limit superparticular comma of about 3.8 cents. It is the amount by which a stack consisting of 7/6 and 20/19 falls short of 16/13, and the difference between 35/24 = (7/6)(5/4) and 19/13. By tempering it out is defined the abnobismic temperament, which enables the abnobismic chords.
Etymology
The name abnobisma was named by Xenllium in 2023. It refers to 456 Abnoba, the asteroid. Which in turn was named after a Celtic goddess.
