Kleismic rank three family

Revision as of 11:40, 23 April 2021 by FloraC (talk | contribs) (Cleanup (1/2))

These are the rank three temperaments tempering out the kleisma, 15625/15552. If nothing else is tempered out we have a 7-limit planar temperament, with an 11-limit comma we get an 11-limit temperament, and so forth.
