Nessafof

Cryptically named by Petr Pařízek in 2011[2], nessafof adds the landscape comma and has a third-octave period. The name actually refers to the fact that it has a neutral-second generator, and that a semi-augmented fourth, stacked 5 times, makes 5/1[1].

Dodifo

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

Also named by Petr Pařízek in 2011, dodifo refers to the (tetraptolemaic) double-diminished fourth, which is a generator of this temperament[1]. The extension here is a less accurate 7-limit intepretation.
