== Luminal ==
Considered below are geb, stockhausenic, decimetra, and luminal, in the order of increasing [[badness]].
Luminal is the intersection of [[Meter|metric]] and [[lux]], tempering out [[3025/3024]] in the 11-limit, [[2080/2079]], [[4096/4095]] in the 13-limit, and [[1156/1155]] and [[2601/2600]] in the 17-limit.  
 
== 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 {{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]]).

== Stockhausenic ==
Stockhausenic may be described as the {{nowrap| 140 & 183 }} temperament, and has a generator chain of ~16/15 (or ~15/8, shown below), relating it to [[25ed5]]. It was named by Xenllium in 2021 after {{w|Karlheinz Stockhausen}} for his experimental use of 25ed5.

== Stockhausenic ==
== Luminal ==
The stockhausenic temperament (140 & 183, named after [[Wikipedia:Karlheinz Stockhausen|Karlheinz Stockhausen]]) is related to [[25ed5]] tuning, and tempers out the hemfiness comma (saquadru-atriyo), 4096000/4084101 = {{monzo| 15 -5 3 -5 }}.
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.

The geb temperament (171 & 506, named after the earth god of ancient Egyptian religion) tempers out the meter and the [[euzenius comma]] (78125000/78121827) as well as [[scheme comma]] (14348907/14336000) in the 7-limit. [[Osiris]] (171 & 670, named after the eldest son of Geb) tempers out the same 5-limit comma as the geb, but with the [[2401/2400|breedsma]] rather than the meter tempered out.
