1-9-11-13 stellated hexany
A 13-limit stellated Hexany. This creates a scale of 1 143/128 9/8 1287/1024 11/8 99/64 13/8 117/64 2/1, with steps of 143/128 144/143 143/128 128/117 9/8 104/99 9/8 128/117. This only adds two steps to the base hexany, but they are well positioned to fill its large gaps without reducing the size of the smallest step, although there is still only one fifth to be found, which is sharp by 352/351, making this a definite improvement melodically, but still not great for constructing chord sequences.
