Quartonic

Quartonic tempers out the quartonic comma, [3 -18 11⟩ = 390625000/387420489 in the 5-limit. This temperament can be described as 26 & 27 temperament, which tempers out the orwellisma and the octagar comma, 4000/3969. The name "quartonic" means quarter-tone, which is the generator of this temperament (representing ~36/35 and ~40/39). Alternative extension yarman (80 & 159) slices the quartonic generator in three.
