Manganese

Manganese is the simplest 5-limit 25th-octave temperament by TE simple badness at 0.1 cent error [1].

Subgroup: 2.3.5

Comma list: [211 50 -125

Mapping[25 2 43], 0 5 2]]

mapping generators: ~[76 18 -45 = 1\25, ~[54 13 -32 = 361.189

Optimal tuning (CTE): ~[54 13 -32 = 361.189

Supporting ETs: 525, 1000, ...

Semimanganese

While manganese is a rather bulky temperament, splitting the generator in half lends itself to a high-limit interpretaton, which can be described as the 525 & 2000 temperament.
