1-3-7-9-11-13 pentadekany

A 13-odd-limit pentadekany. This creates a scale of 1 33/32 13/12 9/8 7/6 39/32 21/16 11/8 143/96 3/2 77/48 13/8 7/4 11/6 91/48 2/1, with steps of 33/32 104/99 27/26 28/27 117/112 14/13 22/21 13/12 144/143 77/48 78/77 14/13 22/21 91/88 96/91. With 8 perfect fifths, lots of intervals slightly smaller than a 12edo semitone and only two comma steps that are difficult to use melodically, this has a lot of compositional potential, although the absence of factors of 5 means the thirds tend to have quite different flavours from 12edo ones.
