what's that third temperament?

that fifth one -- we all know what it is, but how come it's not
consistent with anything, even 22?

It's what I've been calling hemififths. It has 2401/2400 and 5120/5103
for a TM comma basis, and showed up in the recent choma postings as
having Hemififths[48] for 25/24 and Hemififths[34] for 36/35.

It's probably not worth bothering about, Paul. No one's ever likely to
use it. :)

It looks like there was a bug, which isn't in the current version, that stops the reverse ET lookup working where the period and octave are not the same. The static files have been phased out in favor of the CGI script, which doesn't even show the ETs for now.
