Distinct consistency limit	7

587edo is consistent to the 7-odd-limit, but the error of harmonic 3 is quite large. With good approximations to harmonics 5, 7, 9, 11, and 13, it commends itself as a 2.9.5.7.11.13 subgroup tuning.

Using the patent val, however, the equal temperament tempers out 19683/19600 and 703125/702464 in the 7-limit, providing the optimal patent val for the 19 & 183 temperament and the planar temperament cataharry tempering out 19683/19600.
