1-5-7-9 stellated hexany
A 7-limit stellated Hexany. This creates a scale of 1 35/32 9/8 315/256 5/4 45/32 7/4 63/32 2/1, with steps of 35/32 36/35 35/32 64/63 9/8 56/45 9/8 64/63. Since the only two notes this adds to the base hexany are a couple of comma steps which do not even decrease the size of the largest step and there are no perfect fifths, this is distinctly suboptimal for its scale size and mainly just increases the amount of dissonance available, making it highly xenharmonic.
