1308edo is distinctly consistent to the 21-odd-limit, and is the 15th zeta gap edo. With 23/17 barely missing the line, it has reasonable approximations up to the 37-limit.
The equal temperament tempers out [37 25 -33⟩ (whoosh comma) and [-46 51 -15⟩ (171 & 1137 comma) in the 5-limit; 250047/250000, 2460375/2458624, and [47 4 0 -19⟩ in the 7-limit; 9801/9800, 151263/151250, 234375/234256, and 67110351/67108864 in the 11-limit; 4225/4224, 6656/6655, 50193/50176, 91125/91091, and 655473/655360 in the 13-limit; 2601/2600, 5832/5831, 11016/11011, 11271/11264, 12376/12375, and 108086/108045 in the 17-limit; 5491/5488, 5776/5775, 5985/5984, 6175/6174, 10241/10240, and 10830/10829 in the 19-limit.
