5-9-11-13 by 3/2 bihexany

A 13-odd-limit bihexany. This creates a scale of 1 13/12 11/10 143/120 11/9 13/10 13/9 3/2 143/90 33/20 11/6 39/20 2/1, with steps of 13/12 66/65 13/12 40/39 117/110 10/9 27/26 143/135 27/26 10/9 117/110 40/39. This fills the large gap in the base hexany quite effectively and provides a decent selection of both familiar and xenharmonic chords, with the ones on the root and Ab being particularly close to 12edo. Some of the intervals are below the optimal melodic size, but none are so small as to blur into one-another, letting you create both consonance and dissonance using it.
