A 13-odd-limit Dekany. This creates a scale of 1 13/12 33/28 9/7 39/28 3/2 11/7 143/84 11/6 13/7 2/1, with steps of 13/12 99/91 12/11 13/12 14/13 22/21 13/12 14/13 78/77 14/13. This a detemper of bleu, a chain of 12/11's, 13/12's and 14/13's that reaches 3/2 after 5 steps with a couple of close notes distinguished that would be combined in a regular temperament. As a nonatonic scale, it is excellent, and it also has three perfect fifths to provide points of stability, plus an extra one which is sharp by 144/143, although they are all clustered on one side of the scale.
