(convergent)
190537 equal divisions of the octave (abbreviated 190537edo or 190537ed2), also called 190537-tone equal temperament (190537tet) or 190537 equal temperament (190537et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 190537 equal parts of about 0.0063 ¢ each. Each step represents a frequency ratio of 21/190537, or the 190537th root of 2. It is the denominator of the next convergent for log23 past 111202, with another such convergent not occurring until 10590737.
Theory
190537edo has a consistency limit of 11, which is rather impressive for a convergent. However, it is strongest in the 2.3.7.17.23 subgroup. Notably, it is the first member of the log23 convergent series with a 3-2 telicity k-strength greater than 1 since 665edo and it even surpasses 665edo in telicity k-strength. However, the downside is that the step size is many times smaller than the JND. The 3-limit comma this edo tempers out has been named the Archangelic comma.
