I'm interested in these scales...

Not sure of the significance of the - in -125. I realize
that might have been Gene.

I've never noticed "generators" being expressed as larger
than "periods". Why? Can't we just reduce by the periods
here, getting

350.9775006

and

600., 128.512337

resp.?

Again, sorry if this is more of a question for the poster
of the >>'d text (Gene?).

By the way, do these temperaments have names?

yup. anyway, this is a negri scale, yes?

it is. but the answer is yes, you can so reduce by the periods. gene
was just trying to give a "hermite-reduced basis" or some such
abstractly interesting form for the generators.

many of them do, thanks to gene . . .

Is there a way for people to look them up?

Should I put up a web page? Dave, do you have an objection?

Graham's catalog is neither complete or up to date, last I
checked.

The existence of a single resource is a lot to ask, I know...

I'm perfectly willing to put up web pages of named temperaments.
