92 equal divisions of the tritave, perfect twelfth, or 3rd harmonic (abbreviated 92edt or 92ed3), is a nonoctave tuning system that divides the interval of 3/1 into 92 equal parts of about 20.7 ¢ each. Each step represents a frequency ratio of 3^1/92, or the 92nd root of 3.

Theory

92edt is related to 58edo, but with the 3/1 rather than the 2/1 being just. The octave is about 0.9414 cents compressed. Like 58edo, 92edt is consistent to the 18-integer-limit.
