== Swetneus ==
== Swetneus ==
The swetneus temperament takes its name from the fact that an approximate swetismic neutral second, ~49/45, is the generator.
Swetneus tempers out the [[trimyna comma]] and may be described as the {{nowrap| 58 & 91 }} temperament. It takes its name from the fact that the generator is [[~]][[49/45]], a [[neutral second]] that is a [[swetisma]] away from [[12/11]]. Note that in the data that follow, the generator is its [[octave complement]], ~[[90/49]], so that twenty of them reach the [[interval class]] of [[3/1|3]]. In the [[11-limit]], this generator is equated with not [[11/6]] but [[81/44]].

== Majvamoid ==
== Majvamoid ==
The ''majvamoid'' temperament (149 & 183) is an extension of the [[Subgroup temperaments #No-sevens subgroup|majvam]] temperament which tempers out the cataharry comma and the quasiorwellisma (29360128/29296875, sazoquinbigu) in the 7-limit.
Named by [[Xenllium]] in 2021, majvamoid tempers out the [[quasiorwellisma]] and may be described as the {{nowrap| 149 & 183 }} temperament. It is an [[extension]] of the [[majvam]] temperament.
