1-5-7-9-11-15 pentadekany

A 15-odd-limit pentadekany. This creates a scale of 1 33/32 11/10 9/8 99/80 21/16 11/8 7/5 3/2 63/40 27/16 7/4 9/5 15/8 77/40 2/1, with steps of 33/32 16/15 45/44 11/10 35/33 22/21 56/55 15/14 21/20 15/14 28/27 36/35 25/24 77/75 80/77 2/1. With 5 perfect fifths, plus several more imperfect ones that still fall into the diatonic range, such as the 225/224 flat one above 15/8 and and the 100/99 sharp one above 99/80, this is quite strong both melodically and harmonically, with the only melodically dubious step between 11/7 & 7/5. While it does have a perfect fifth above the root, the most stable mode is probably the one above the 3/2, as that has both 5-limit major & minor chords above it.
