Theory

1643edo is the multiple of two very famous EDOs: 31edo and 53edo.

The best subgroup for it is the 2.3.5.11.13 subgroup. Nonetheless, it provides the optimal patent val for the 13-limit version of iodine temperament, which tempers out the Mercator's comma and has a basis 6656/6655, 34398/34375, 43904/43875, 59535/59488.
