A synched 5120/5103 scale example

In message

/tuning-math/message/10065

I noted that the 3x3x3 chord cube, extended to quintads, produces a 47
note scale which is a good candidate for hemififths tempering (to a 46
note scale, eliminating a 2401/2400 step). As an example of the
closeness of hemififths and 5120/5103 synch tuning, here is the
inversion of that scale tuned to that tuning; since the 2401/2400 step
is not eliminated but shrunk, I picked one of the two nearby steps to
produce the scale. It has 20 otonal tetrads and 17 otonal quintads, of
which one is anomalous; it still has synched beating of the major,
minor and fifth components (brat -1), but the 7 is 0.182 cents sharp
rather than 0.423 cents sharp.

Eduardo Sabat-Garibaldi introduced the "beta" terminology for
*different* 'commas'; hence "beta 2" and "beta 5" are different, for
example. "Beta" alone doesn't signify any comma according to Eduardo's
system or any other that I know of.

And Wendy Carlos has a temperament by this name.

Beta5 is the only beta Manuel lists, I'll call it something else if
someone has a good suggestion.

Really? What happened to Beta2, Manuel? Any others?
