415EDT is the equal division of the third harmonic into 415 parts of 4.5830cents each, corresponding to 261.8358 edo. It is notable for its impressive consistency records in very high no-evens throdd limits: specifically, it is consistent to the entirety of the no-23s no-47s no-59s add-71 65-throdd limit, and all additional intervals if primes 59, 67, and 73 are added to this are within 60.2% of a step of their patent val approximation. This makes it a potential candidate for the tritave-based version of 311edo, although its performance is not quite as spectacular as that miracle edo.
