'''135/112''', conventionally known as 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 an [[3645/3584|aberdiesis (3645/3584)]], i.e. a [[81/80|syntonic comma (81/80)]] plus a [[225/224|marvel comma (225/224)]]. This interval functionally doubles as a type of augmented second, sharp of the [[19683/16384|Pythagorean augmented second (19683/16384)]] by an [[5120/5103|aberschisma (5120/5103)]]. This gives rise to the more precise name '''aberschismic augmented second'''. In fact it forms the difference between [[9/7]] and [[16/15]].


'''135/112''', the '''septimal wide minor third''', or '''marvelous minor third''', is a [[7-limit]] interval which has the distinction of being almost half of a [[16/11]] minor fifth- in fact, a stack of two 135/112 differs from [[16/11]] by [[200704/200475]], a comma less than two cents in size. As the octave complement of 224/135 this interval functionally doubles as a type of augmented second, nevertheless, because of the relationship between 135/112 and 16/11, one can easily form a triad consisting of 1/1-135/112-16/11, to which one can then add [[135/77]] as a seventh.
This interval has the distinction of being almost half of a [[16/11|undecimal semidiminished fifth (16/11)]] – in fact, a stack of two <u>135/112</u>'s differs from [[16/11]] by a [[200704/200475|"reef comma" (200704/200475)]], which is less than two cents in size. Because of the relationship between <u>135/112</u> 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.
