Rarity

For the 5-limit version of this temperament, see High badness temperaments #Rarity.

Rarity generator is so close to 23/19, and some edos supporting it have good 19th and 23rd harmonics that it is natural to prescribe a 2.3.5.19.23 extension. Since the generator is also mapped to 368/225, this means that 4275/4232 is tempered out.
