1342edo is consistent to the 9-odd-limit, but there is a large relative delta for harmonics 7 and 11. Its notability lies in the utility as every other step of the full 13-limit monster – 2684edo, so it probably makes more sense as a 2.3.5.13 subgroup temperament. In the 5-limit it tempers out kwazy, [-53 10 16⟩, senior [-17 62 -35⟩, and egads, [-36 52 51⟩; in the 2.3.5.13 subgroup it tempers out 140625/140608.

Subsets and supersets
Since 1342 factors as 2 × 11 × 61, 1342edo has subset edos 2, 11, 22, 61, 122, and 671. 2684edo, which doubles it, corrects the harmonics 7 and 11 to near-just qualities.
