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 subsets are analyzed as two scales that share the Tonic and are then combined (as in the diagram above), the resulting scale would have 23 tones in the octave; otherwise, it would have 24.
