1-7-9-11-13-15 pentadekany
A 15-odd-limit pentadekany. This creates a scale of 1 117/112 15/14 9/8 135/112 143/112 9/7 11/8 165/112 11/7 13/8 195/112 99/56 13/7 15/8 2/1, with steps of 117/112 40/39 21/20 15/14 143/135 144/143 77/72 15/14 16/15 91/88 66/65 104/99 105/104 16/15. This has no perfect fifths, with the closest approximation being the 5 cent sharp one above 117/112, giving you only one fairly stable rooting point. As it also has three comma steps that blur into their neighbours, it is not particularly optimal for its size melodically either, making this one only of interest to hardcore lovers of xenharmonic sounds.
