>Periodicity blocks? They aren't epimorphic/CS.
Well, I thought we decided that block = epimorphic + convex.
It looks to me like the two glumma family is convex. Not
epimorphic, eh? From monz's tuning dictionary, I get that a
scale is epimorphic when there's a single val that can map
all its degrees to integers. I'm missing some details. Can
you show how one of these scales is not "epimorphic".
"epimorphic/CS" -- forgive me if we've been over this (I
can't find anything in the archives), but does epimorphic
equal constant structures?

That's right, and I think Paul had decided that blocks whose
smallest 2nd was larger than their smallest unison vector
would be... something. Proper? CS? I forget.
