'''5767168/5764801''', the '''amaranthinisma''', is an [[unnoticeable comma|unnoticeable]] [[11-limit]] [[comma]] between a stack of eight [[8/7]]'s and [[32/11]] (one octave above [[16/11]]), measuring 0.711 cents; it can also be expressed as the difference between [[99/98]] and two [[1029/1024|gamelismas (1029/1024)]]. Since both 99/98 and 1029/1024 are tempered out in undecimal [[mothra]], this comma is also tempered out.

Tempering out this comma in the full [[11-limit]] results in the rank-4 '''amaranthinismic temperament''', and tempering it out in the 2.7.11 [[subgroup]] results in the rank-2 [[No-threes subgroup temperaments#Amaranthine|amaranthine]] temperament.

As its order of 11 is one, any [[7-limit]] temperament can be immediately extended to the 11-limit in theory by tempering out this comma. To make practical sense, however, it requires low complexity and high accuracy of 8/7.
