The septimal minor third ~[[7/6]] (11\49) is near-just, which suggests its use as a generator, as in [[Orwell]]; however, it is too close to just for actual Orwell eemperament, and so a stack of it manages to miss all of the intervals characteristic of Orwell, other than a fairly flat classic minor sixth ~[[8/5]] — hence [[Orwellismic_temperaments#Infraorwell|Infraorwell]]. | |||
==== 3L 4s (may not be correct mapping) ==== | |||
[[Bryan Deister]] has demonstrated a [[3L 4s]] version of this (with an 11:4 step ratio), in [https://www.youtube.com/shorts/VmUIxWb8NCY ''49edo prelude''] (2026). (Suspect that this is not the correct mapping — it misses notes, and does not match the unlit keys in the upper left corner.) | |||

==== 4L 5s (proposed and untested) ==== | |||
It is also possible to produce a forward chroma [[4L 5s]] (gramitonic, 6:5 step ratio) [[Orwellismic_temperaments#Infraorwell|Infraorwell]] mapping for [[49edo]]. This mapping gets all notes in each octave and has a range of a bit over 4 octaves. Apart from straight right (forward chroma version) or straight down-right (reverse chroma version), the most accessible generator is 11\49, the aforementioned septimal minor third. | |||
