1-3-9-11-13-15 eikosany

A 15-odd-limit eikosany. This creates a scale of 1 65/64 13/12 55/48 11/9 715/576 5/4 143/108 65/48 11/8 13/9 143/96 55/36 13/8 5/3 55/32 65/36 11/6 15/8 143/72 2/1, with steps of 65/64 16/15 55/52 16/15 65/64 144/143 143/135 45/44 66/65 104/99 33/32 40/39 117/110 40/39 33/32 104/99 66/65 45/44 143/135 144/143. With 12 perfect fifths, but also a fair number of wolf ones and other close clusters of notes, this is another eikosany that can be used in both consonant and highly dissonant ways as long as you have an instrument that can handle this number of notes per octave and can keep track of which notes are mapped where.
