80 equal divisions of the 6th harmonic (abbreviated 80ed6) is a nonoctave tuning system that divides the interval of 6/1 into 80 equal parts of about 38.8 ¢ each. Each step represents a frequency ratio of 61/80, or the 80th root of 6.
80ED6 is related to 31edo, but with the 6/1 rather than the 2/1 being just. This stretches the octave by about 2 cents.
