1-11-13-15 stellated hexany
A 15-odd-limit stellated Hexany. This creates a scale of 1 2145/2048 143/128 165/128 11/8 195/128 13/8 15/8 2/1, with steps of 2145/2048 16/15 15/13 16/15 195/176 16/15 15/13 16/15. This only adds two steps to the base hexany, but they are well positioned ones that reduce the size of the largest step while not introducing any intervals too small to be melodically useful, making the scale surprisingly concordant considering how many steps fall right between the cracks of the 12edo keyboard.
