'''43ED4''' is the [[Ed4|equal division of the double octave]] into 43 parts of 55.8140 [[cent|cents]] each (every second step of [[43edo]]). It is closely related to [[34edt]], but the patent vals differ on the mapping for 13. Using the patent val, it tempers out 49/48, 81/80, and 16128/15625 in the 3.4.5.7 subgroup; 77/75, 176/175, 891/875, and 1331/1280 in the 3.4.5.7.11 subgroup; 121/117, 144/143, 147/143, 175/169, and 729/715 in the 3.4.5.7.11.13 subgroup.
