1-3-5-9-13-15 pentadekany
A 15-odd-limit pentadekany. This creates a scale of 1 65/64 13/12 9/8 39/32 5/4 65/48 45/32 3/2 25/16 13/8 5/3 15/8 2/1, with steps of 65/64 16/15 27/26 13/12 40/39 13/12 27/26 16/15 25/24 26/25 40/39 9/8 16/15. (5/4 and 15/8 appear twice, reducing it to a 13 note scale) While it does contain a complete 5-limit diatonic scale and so it is entirely possible to play familiar sounding music in it, the extra tridecimal notes are quite lopsided, with a wolf octave that blurs into the regular one and most of the notes on one side of the scale, leaving this not particularly optimal for the number of notes it has.
