1-5-7-9 hexany

A 9-odd-limit Hexany. This creates a scale of 1 9/8 7/5 63/40 7/4 9/5 2/1, with steps of 9/8 56/45 9/8 10/9 36/35 10/9. This forms an incomplete detemper of the 6edo scale with one note omitted and another split into two different notes a quartertone apart, making for a quite xenharmonic sound. Since there are no 3/2's to be found anywhere, the most stable notes are probably the two with a 5/4 above them, particularly the one with both 8:9:10 harmonic and 9/9 9/8 9/7 subharmonic sequences above it.
