184edo is closely related to 46edo, but the patent vals differ on the mapping for 5. It is inconsistent to the 5-limit and higher limit, with five mappings possible for the 11-limit: 184 292 427 517 637] (patent val), 184 291 427 516 636] (184bde), 184 292 428 517 637] (184c), 184 292 427 516 636] (184de), and 184 292 427 517 636] (184e).

Using the patent val, it tempers out the tetracot comma, 20000/19683 and 286102294921875/281474976710656 in the 5-limit; 3125/3087, 10976/10935, and 65536/64827 in the 7-limit; 540/539, 896/891, 6875/6804, and 12005/11979 in the 11-limit; 352/351, 364/363, 640/637, and 676/675 in the 13-limit.

Using the 184bde val, it tempers out 129140163/125000000 and 553584375/536870912 in the 5-limit; 225/224, 50421/50000, and 38263752/37515625 in the 7-limit; 385/384, 540/539, 15309/15125, and 43923/43750 in the 11-limit; 351/350, 625/624, 1001/1000, 4455/4394, and 7203/7150 in the 13-limit. Using the 184bdef val, 1573/1568, 1575/1573, 1701/1690, 1716/1715, and 3042/3025 are tempered out in the 13-limit.

Using the 184c val, it tempers out the diaschisma, 2048/2025 and the sensipent comma, 78732/78125 in the 5-limit; 2401/2400 and 65536/64827 in the 7-limit; 176/175, 896/891, 3773/3750, and 14641/14580 in the 11-limit; 351/350, 352/351, 364/363, and 9295/9261 in the 13-limit.

Using the 184de val, it tempers out 1029/1024, 153664/151875, and 214375/209952 in the 7-limit; 896/891, 1331/1323, 2401/2376, and 3773/3750 in the 11-limit; 196/195, 676/675, 1001/1000, 3185/3168 in the 13-limit.

Using the 184e val, it tempers out 385/384, 3388/3375, 9801/9800, and 12100/11907 in the 11-limit; 275/273, 572/567, 640/637, and 847/845 in the 13-limit.
