143edo

143edo is the equal division of the octave into 143 parts of approximately 8.392¢ each. The 143b val provides a tuning almost identical with that of the POTE tuning for 7-limit meantone.

As 143 is 11*13, 143edo allows the polymicrotonal juxtaposition of 11edo and 13edo:

If the 11edo and 13edo sub-scales share one tone (as in the diagram above), the resulting scale would have 23 tones in the octave; otherwise, it would have 24.
