143edo is only consistent to the 5-odd-limit, and the error of the harmonic 3 is quite large.
The 143b val provides a tuning almost identical with that of the POTE tuning for 7-limit meantone.

Subsets and supersets
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.
