'''135/112''', the '''septimal wide minor third''', or '''marvel-ptolemaic minor third''', is a [[7-limit]] interval that is sharp of the [[32/27|Pythagorean minor third]] by [[3645/3584]], i.e. a [[81/80|syntonic comma]] plus a [[225/224|marvel comma]]. This interval functionally doubles as a type of augmented second, sharp of the [[19683/16384|Pythagorean augmented second]] by [[5120/5103]]. This gives rise to the name '''hemifamity augmented second'''.

'''135/112''', the '''septimal wide minor third''', or '''marvel-ptolemaic minor third''', is a [[7-limit]] interval that forms the difference between [[9/7]] and [[16/15]]. It is sharp of the [[32/27|Pythagorean minor third]] by [[3645/3584]], i.e. a [[81/80|syntonic comma]] plus a [[225/224|marvel comma]]. This interval functionally doubles as a type of augmented second, sharp of the [[19683/16384|Pythagorean augmented second]] by [[5120/5103]]. This gives rise to the name '''hemifamity augmented second'''.

This interval has the distinction of being almost half of a [[16/11]] semidiminished fifth – in fact, a stack of two 135/112's differs from [[16/11]] by [[200704/200475]], a comma less than two cents in size. Because of the relationship between 135/112 and 16/11, one can easily form a triad consisting of 1–135/112–16/11, to which one can then add [[135/77]] as a seventh.
