← 40edt 41edt 42edt →
Prime factorization 41 (prime)
Step size 46.3891 ¢ 
Octave 26\41edt (1206.12 ¢)
Consistency limit 10
Distinct consistency limit 9

Division of the third harmonic into 41 equal parts (41edt) is related to 26 edo, but with the 3/1 rather than the 2/1 being just. The octave is about 6.1178 cents stretched and the step size is about 46.3891 cents. Unlike 26edo, it is only consistent up to the 10-integer-limit, with discrepancy for the 11th harmonic.

41edt is related to the regular temperament which tempers out 823543/820125 and 2199023255552/2197176384375 in the 7-limit, which is supported by 181, 207, 388, 569, and 595 EDOs.
