Original Wikitext content:

Breed is a 7-limit microtemperament which tempers out 2401/2400. While it is so accurate it hardly matters what is used to temper it, or whether it is tempered at all, 2749et will certainly do the trick.

===Vital statistics===
Comma c = 2401/2400
7- and 9-limit minimax tuning: 3 and 5 just, 7 1/4c flat
Eigenmonzos: 6/5 and 5/4 (or 4/3)
Lattice basis: 49/40 length 0.7858 8/7 length 1.1241
Angle(49/40, 8/7) = 107.367 degrees
Map to lattice: [<0 2 -1 0|, <0 0 -2 -1|]
EDOs: 441, 612, 2308, 2749

==11-limit children==

===Jove, aka Wonder=== 
Jove, formerly known as wonder, tempers out 243/242 and 441/440. Wonder has been deprecated as a name due to conflict with another temperament also given that name. Jove converts breed into an 11-limit temperament via 441/440, which equates 49/40 with 11/9, and 243/242, which tells us 11/9 can serve as a neutral third. While jove is no longer a super-accurate microtemperament like breed, it has the advantage of adjusting its tuning to deal with the 11-limit. 72, 130 and 171 are good edos for jove, and if that doesn't suit there's 476edo.
