+'''20/11''' the '''small undecimal neutral seventh''' or '''undecimal supraminor seventh''' is an [[11-limit]] [[interval]] measuring about 1035{{cent}} in size. It can be used as a seventh in chords like [[11:14:16:20]] and [[44:55:66:80]]. Three intervals of 20/11 exceed [[6/1]] by [[4000/3993]], a comma about 3{{c}} in size.

+== Approximation ==
-[[Category:Over-11]]
+/11 is approximated extremely precisely by [[80edo]] and its multiples, with a chain of eighty 20/11's failing to close at the octave by a mere third of a cent, close enough that you could theoretically tune an instrument to 80edo by ear using it if you had the patience.
