3-7-13-15 by 7/5 bihexany

A 13-limit bihexany. This creates a scale of 1 15/14 13/12 65/56 5/4 13/10 7/5 3/2 91/60 13/8 7/4 13/7 2/1, with steps of 15/14 91/90 15/14 14/13 26/25 14/13 15/14 91/90 15/14 14/13 52/49 14/13. This is another way of expanding out the base hexany into a bihexany that cancels out many of the composite ratios to produce simpler ones, including a 3/2 above the root. Like the 3-7-13-15 by 4/3 bihexany, this expands it out to a greater detempered subset of negri, in this case a 9L 1s one with only two notes split into microtonal variants. This makes it the melodically strongest of these options, but gives you fewer options to evade wolf notes when constructing chords.
