3159811 equal divisions of the octave (abbreviated 3159811edo or 3159811ed2), also called 3159811-tone equal temperament (3159811tet) or 3159811 equal temperament (3159811et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 3159811 equal parts of about 0.00038 ¢ each. Each step represents a frequency ratio of 21/3159811, or the 3159811th root of 2.

3159811edo is consistent in the 65-odd-limit with a lower relative error than any previous equal temperaments in the 61-limit. It is the smallest EDO which is purely consistent[idiosyncratic term] in the 63-odd-limit (i.e. does not exceed 25% relative error on the first 63 harmonics of the harmonic series).
