262EDT is the equal division of the third harmonic into 262 parts of 7.2594 cents each, corresponding to 165.3036 edo (similar to every third step of 496edo). It doubles 131edt, which is consistent to the no-evens 25-throdd limit, and is contorted with it to the no-twos 23-limit, but it improves the representation of a number of higher primes so that 262edt is consistent to the entire no-evens 53-throdd limit with the exception of only 9 inconsistent interval pairs (19/13, 19/17, 25/19, 41/19, 41/37, 47/17, 47/25, 47/41, and 49/41, and their complements), all of which are still within 60% of a step off.
