14348edo is a strong 17-limit system, with a lower 17-limit [[relative error]] than any smaller edo aside from [[7033edo|7033]]. It is also distinctly [[consistent]] in the 29-odd-limit, and has a lower 23-limit [[relative error]] than any lower equal temperaments aside from [[2460edo|2460]], [[8269edo|8269]], [[8539edo|8539]] and [[11664edo|11664]]. Besides all that, it is a [[The Riemann zeta function and tuning #Zeta EDO lists|zeta peak, integral and gap edo]], which has to do with its higher limit capability—it has lower relative errors than any smaller equal temperaments in the 41-limit and way beyond. The only inconsistent interval pair in the [[69-odd-limit]] is ([[31/29]], [[58/31]]) with 50.2% relative error. [[71038ed31]], a compressed version of 14348edo, is consistent to the 56-[[integer-limit]], though overall stretching the octave is better. An EDO of similar size that is consistent this far without stretch (to the [[57-odd-limit]]) is [[20567edo]].

14348 equal divisions of the octave (abbreviated 14348edo or 14348ed2), also called 14348-tone equal temperament (14348tet) or 14348 equal temperament (14348et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 14348 equal parts of about 0.0836 ¢ each. Each step represents a frequency ratio of 21/14348, or the 14348th root of 2.

14348edo is a strong 17-limit system, with a lower 17-limit relative error than any smaller edo aside from 7033. It is also distinctly consistent in the 29-odd-limit, and has a lower 23-limit relative error than any lower equal temperaments aside from 2460, 8269, 8539 and 11664. Besides all that, it is a zeta peak, integral and gap edo, which has to do with its higher limit capability—it has lower relative errors than any smaller equal temperaments in the 41-limit and way beyond. The only inconsistent interval pair in the 69-odd-limit is (31/29, 58/31) with 50.2% relative error. Thus the full 67-limit interpretation using the patent val is obvious, though it may be preferable to omit either prime 29 or 31.

An edo of similar size with full consistency to a very high limit (57-odd-limit) is 20567edo.
