11859211/11859210
11859211/11859210, the tredekisma, is the smallest superparticular ratio in the 19-limit and 23-limit.
| Interval information |
reduced
It can be seen as the differencebetween a stack of a 25/16 plus a minisma plus a Saquadnu comma, and a diminished fifth plus two Axirabian limmas:
(25/16)(4096/4095)(131072/130321)÷(1024/729)(128/121)^2
Temperaments
Only being 0.00014 cents, it is an insanely, unfathomably narrow comma; hundreds of times narrower than well known atomic commas like the Chalmersia and the Kirnberger's atom. As such, tempering out or fudging this either way are aurally identical to JI to human ears. It is notably tempered out in 270edo thanks to its very well approximated 2.3.5.7.11.13.19, hence its name; also tempered out in other edos like 94, 118, 152, 364, among others.
