Triwellismic temperaments
Triwellismic rank-two temperaments temper out the triwellisma, [1 -1 -7 6⟩ = 235298/234375, the difference seven 7/5s and septimal triple-compound sub-fourth (21/16 plus three octaves).
Temperaments discussed elsewhere include ammonite, chromat, decal, fourfives, hemiwürschmidt, nusecond, semidimfourth, sextilischis, tritonic, triwell and undecental.
Interaufo
The name "interaufo" means an augmented fourth interval between 45/32 (classic diatonic tritone) and 729/512 (Pythagorean tritone). The interaufo temperament (159&161) tempers out the same 5-limit comma as the untriton, but has a generator as 24/17-wide tritone, three generators makes 45/32 and five of them makes 7/5 with octave reduction.
