2554 equal divisions of the octave (abbreviated 2554edo or 2554ed2), also called 2554-tone equal temperament (2554tet) or 2554 equal temperament (2554et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 2554 equal parts of about 0.47 ¢ each. Each step represents a frequency ratio of 21/2554, or the 2554th root of 2.
2554edo is a remarkable very high limit equal temperament. It is consistent through the 41-odd-limit distinctly, tempering out 3025/3024, 4675/4674, 6325/6324, 7106/7105, 7216/7215, 7905/7904, 12155/12152, 13300/13299, 13950/13949, 14652/14651, 56265/56252, and 92701/92690. It provides the optimal patent val for the rank-4 temperament tempering out 3025/3024, the lehmerisma, and thor, the rank-3 temperament also tempering out 4375/4374. It is enfactored in the 7-limit, with the same mapping as 1277edo.
