1-3-9-11 stellated hexany
An 11-odd-limit stellated Hexany. This creates a scale of 1 33/32 9/8 297/256 11/8 3/2 99/64 27/16 2/1, with steps of 33/32 12/11 33/32 32/27 12/11 33/32 21/11 32/27. While 6 of the 8 notes do have perfect fifths above them, this is still highly xenharmonic sounding due to the quartertone steps and large gaps in the scale, making it quite lopsided, but not so much that the notes start to blur into one-another.
