I have Flora's python code so I can add the optimal et sequence now
Normalize the mapping; unify the precision; optimal ET sequence

This temperament, which can be described as 7c & 12c or 19 & 64, was first named by [[User:Jerdle|Jerdle]] in [[User:Jerdle/The Ocean]] page. It is generated by a [[19edo]]/[[flattone]]-like fifth, but finds 5/4 at -15 generators (a double-diminished fourth) rather than a major third. It is of very high badness, and probably not that practical, but perhaps the 19-note MOS could be used for some kind of 19edo [[well temperament]]. Only two [[patent val]]s support this temperament ([[19edo]] and [[64edo]]), but additionally, the [[dual-fifth]] systems [[83edo]] and [[102edo]] support this temperament with their second-best fifths (83b and 102b), and those are probably the best tunings. Note that octave-stretching significantly reduces the error on all harmonics.
