(WIP, catalog of 3.5.7 subgroup rank two temperaments will eventually be redirected here)
This is a collection of subgroup temperaments which omit the prime harmonic of 2. These are all nonoctave scales using a period of a tritave rather than an octave.
BPS
Subgroup: 3.5.7
Comma list: 245/243
Sval mapping: [⟨1 1 2], ⟨0 -2 1]]
Sval mapping generators: ~3, ~9/7
Optimal tuning (POTE): ~3 = 1\1edt, ~9/7 = 440.4881
