1-7-9-13 stellated hexany
A 13-limit stellated Hexany. This creates a scale of 1 9/8 91/64 819/512 13/8 7/4 117/64 63/32 2/1, with steps of 9/8 91/72 9/8 64/63 14/13 117/112 14/13 64/63. This only adds two steps to the base hexany, both of which are comma steps of 64/63 that mostly make the scale more dissonant and are not very useful melodically. While it does not approximate any perfect fifths, it does have one major third that is only out from 5/4 by 4096/4095, which does provide some degree of stability, but overall, this is still highly xenharmonic and quite heavily clustered on one side.
