== Luminal ==
== Geb ==
Luminal may be described as the {{nowrap| 128 & 183 }} temperament. In the [[11-limit]] it extends via [[skadi]], the metric extension tempering out 3025/3024, the [[lehmerisma]], and joins with [[lux]] so that it also tempers out 131072/130977, the [[olympia]]. It was named by [[Flora Canou]] in 2021 following the naming of lux, whose name is the SI unit for illuminance, and lx⋅m<sup>2</sup> is lumen, the SI unit for luminous flux.  
: ''For the 5-limit version, see [[Syntonic–chromatic equivalence continuum #Geb (5-limit)]].''
 
Geb tempers out the [[scheme comma]] as well as the [[euzenius comma]], and may be described as {{nowrap| 164d & 171 }} temperament. It was named by [[Xenllium]] in 2021 after the earth god of ancient Egyptian religion and the father of Osiris; the latter being the name of a temperament that tempers out the same 5-limit comma as the geb (→ [[Breedsmic temperaments #Osiris]]).

This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

This is a collection of rank-2 metric microtemperaments, which temper out the meter (monzo[-11 2 7 -3, ratio: 703125/702464).

Temperaments discussed elsewhere include:

Considered below are geb, stockhausenic, decimetra, and luminal, in the order of increasing badness.

Geb

For the 5-limit version, see Syntonic–chromatic equivalence continuum #Geb (5-limit).

Geb tempers out the scheme comma as well as the euzenius comma, and may be described as 164d & 171 temperament. It was named by Xenllium in 2021 after the earth god of ancient Egyptian religion and the father of Osiris; the latter being the name of a temperament that tempers out the same 5-limit comma as the geb (→ Breedsmic temperaments #Osiris).

Luminal

Luminal may be described as the 128 & 183 temperament. In the 11-limit it extends via skadi, the metric extension tempering out 3025/3024, the lehmerisma, and joins with lux so that it also tempers out 131072/130977, the olympia. It was named by Flora Canou in 2021 following the naming of lux, whose name is the SI unit for illuminance, and lx⋅m2 is lumen, the SI unit for luminous flux.
