A 15-odd-limit dekany. This creates a scale of 1 65/64 13/12 5/4 65/48 25/16 13/8 5/3 15/8 2/1, with steps of 65/64 16/15 15/13 13/12 15/13 26/25 40/39 9/8 16/15. (5/4 appears twice as the reduced products of 1x15 & 3x5.) This continues the pattern of the first few 15-odd-limit dekanies of having repeated notes and multiple perfect fifths, but not one above the root, requiring rotating to find the most consonant mode.
