It is a type of quartertone that differs from [[33/32]] by [[243/242]], and is itself the interval left over after subtracting 33/32 from [[2187/2048]]. While many may be accustomed to thinking of 33/32 and 729/704 as "semiaugmented primes", this analysis is only completely accurate when 243/242 is tempered out. This interval differs from the simpler [[28/27]] by the [[symbiotic comma]]. | It is a type of quartertone that differs from [[33/32]] by [[243/242]], and is itself the interval left over after subtracting 33/32 from [[2187/2048]].

== Sagittal notation == | |||
In the [[Sagittal]] system, the downward version of this comma (possibly tempered) is represented by the sagittal {{sagittal | (!) }} and is called the '''11 large diesis''', or '''11L''' for short, because the simplest interval it notates is 11/1 (equiv. 11/8), as for example in F-B{{nbhsp}}{{sagittal | (!) }}. The upward version is called '''1/11L''' or '''11L up''' and is represented by {{sagittal| (|) }}. | |||
