311edo: Difference between revisions
→Intervals: added commentary on the tuning properties of 311edo and on the presence of square-particulars at the beginning of the table |
m →Intervals: correction to 123-odd-limit. 125 is excluded as it is quite inconsistent. |

The 41-limit add-73 add-89 add-101 add-109 add-113 | The 41-limit add-73 add-89 add-101 add-109 add-113 123-odd-limit is represented very close to completely consistently, and as aforementioned, the 77-odd-limit subset of that odd-limit is perfectly consistent, to which a variety of odds can be added that keep perfect consistency, but for comprehensiveness and practical use as a temperament approximating the low-to-mid end of the harmonic series, we consider a larger odd-limit than that which seeks to be more complete. | ||

Therefore, the very beginning of the table (from 0\311 to 3\311 inclusive) is the only part that is not algorithmically generated. | ||
