'''30/19''', the '''small undevicesimal minor sixth''' is a [[19-limit]] interval, 790.8 [[cent]]s in size. In [[Functional Just System]] and [[Helmholtz-Ellis notation]], it is an ''augmented fifth'', obtained by subtracting [[81/80]] and [[513/512]] from the [[~~8192~~/~~6561~~|Pythagorean augmented fifth]], but it may be called the '''Eratosthenes' minor sixth''' as it is flatter than the [[128/81|Pythagorean minor sixth]] by the ''password'' aka ''Eratosthenes' comma'' ([[1216/1215]]), an [[unnoticeable comma]] of about 1.4243 cents.
