135edo is [[consistent]] to the [[7-odd-limit]], but there is a large relative delta for the [[5/1|5th]] and [[13/1|13th]] [[harmonic]]s. | 135edo is [[consistent]] to the [[7-odd-limit]], but there is a large relative delta for the [[5/1|5th]] and [[13/1|13th]] [[harmonic]]s. As every other step of the full 13-limit monster – [[270edo|270et]], 135et probably makes more sense as a 2.3.7.11 [[subgroup]] temperament, where it [[tempering out|tempers out]] the [[garischisma]] and the [[symbiotic comma]]. If we consider the full 13-limit, the flat-tending {{val| 135 214 313 379 467 '''499''' }} (135f) and the sharp-tending {{val| 135 214 '''314''' 379 467 500 }} (135c) are reasonable choices. | ||

Since 135 factors into {{factorization|135}}, 135edo has subset edos {{EDOs| 3, 5, 9, 15, and 45 }}. 270edo, which doubles it, provides good correction for the approximation to harmonics 5, 13, and 19. | Since 135 factors into {{factorization|135}}, 135edo has subset edos {{EDOs| 3, 5, 9, 15, and 45 }}. 270edo, which doubles it, provides good correction for the approximation to harmonics 5, 13, and 19. | ||
