The Twelve Ragisyn Scales

The interval 6561/6250 is shy of a minor semitone of 21/20 by a
ragisma, so we may consider it a RAGIismic minor semitone; together
with the SYNtonic comma of 81/80 we have the name "ragisyn" for this
type of Fokker block. Below I list all twelve of them; the first two
are self-dual, the rest are inversively related in successive pairs.
As before, they all reduce to -3 to 8 under the meantone val.
