The wuerschmidt family tempers out Wuerschmidt's comma, 393216/390625 = |17 1 -8&gt;. Wuerschmidt itself has a generator of a major third, eight of which give a 6; that is, (5/4)^8 * (393216/390625) = 6. Both [[31edo]] and [[34edo]] can be used as wuerschmit tunings, as can [[65edo]], which is quite accurate.

===Augmented family===
===[[Augmented family]]===
The augmented family tempers out the limma of 128/125, and so identifies the major third with 1/3 octave. Hence it has the same 400 cent thirds as [[12edo]], which is an excellent tuning for augmented.

===Dicot family===
===[[Dicot family]]===
The dicot family is a low-accuracy family of temperaments which temper out the chromatic semitone, 25/24, and hence identify major and minor thirds. [[7edo]] makes for a good dicot tuning.
