An 11-odd-limit Hexany. This creates a scale of 1 11/10 9/8 99/80 11/8 9/5, with steps of 11/10 45/44 11/10 10/9 72/55 10/9. With a ratio of more than 12:1 between the largest and smallest steps and a gap of nearly a perfect fourth on one side, this is a very lopsided and xenharmonic hexany that does not approximate common practice music at all.
