1-5-9-17 stellated hexany
A 17-odd-limit stellated Hexany. This creates a scale of 1 17/16 9/8 153/128 5/4 85/64 45/32 765/512 2/1, with steps of 17/16 18/17 17/16 160/153 17/16 18/17 17/16 1024/765. This only adds two notes to the base hexany, which mildly reduce the size of the largest step and increases the number of diatonic fifths available to 4, but only one of them has any useful thirds and there is still a massive gap on the other side of the scale, making it quite limited in modulation ability and also not xenharmonic at all.
