The 23-odd-limit is the set of all rational intervals for which neither the numerator nor the denominator of the frequency ratio exceeds 23, once all powers of 2 are removed. To the 21-odd-limit, it adds 11 interval pairs involving 23.
Below is a list of all octave-reduced intervals in the 23-odd-limit. It contains all the wonders of 94edo.
