(convergent)
Division of the just perfect fifth into 7 equal parts (7EDF) is related to 12 edo, but with the 3/2 rather than the 2/1 being just. The octave is about 3.3514 cents stretched and the step size is about [[1]] cents. The patent val has a generally sharp tendency for harmonics up to 21, with the exception for 11 and 13.
Lookalikes: 12edo, 19ed3, 31ed6
