	'''21/11''', the '''large undecimal diminished octave''' is an [[11-limit]] interval, and the octave complement of [[22/21]]. Of note is that the Huygens-Fokker Foundation dubs this interval the '''undecimal major seventh''', which~~, in light of the size of [[33/32]],~~ also makes sense, resulting in this interval being perhaps best classified as a "sevtave" – a type of cross between a seventh and an octave.		'''21/11''', commonly known as the '''large undecimal diminished octave''', is an [[11-limit]] interval, and the octave complement of [[22/21]].

			In many notation systems (e.g. [[FJS]], [[HEJI]]), it is an imperfect octave, as it is the octave minus a stack consisting of an [[33/32\|undecimal quartertone (33/32)]] and a [[64/63\|septimal comma (64/63)]], neither of which changes the [[scale\|scale degree]] or [[interval quality\|quality]]. However, it is only sharp of the [[243/128\|Pythagorean major seventh (243/128)]] by a [[896/891\|pentacircle comma (896/891)]]. For this reason it could be called the '''pentacircle major seventh'''.

			Of note is that the Huygens-Fokker Foundation dubs this interval the '''undecimal major seventh''', which also makes sense, resulting in this interval being perhaps best classified as a "sevtave" – a type of cross between a seventh and an octave.
