The 23-odd-limit is the set of all rational intervals which can be written as 2^k(a/b) where a, b ≤ 23 and k is an integer. To the 21-odd-limit, it adds 11 pairs of octave-reduced intervals involving 23.

Below is a list of all octave-reduced intervals in the 23-odd-limit. It contains all the wonders of 94edo.
