35th-octave temperaments

35edo is a tuning system that's not remarkable in its own right from a regular temperament theory perspective, but some of its multiples are either zeta edos like 3395edo, have an exceptionally precise perfect fifth like 665edo, or have high consistency limits like 525edo. In addition, one step of 35edo is close to 50/49 in low limits and 51/50 in the higher limits.

Tritonopodismic (rank-3)

Tritonopodismic tempers out tritonopod comma, the comma which sets 7/5 to 17\35, "one leg", and 10/7 to 18\35, the "other leg". Also it sets 50/49 to be equal to 1\35.
