56/55, the undecimal tritonic comma or konbini comma, is an 11-limit no-threes comma of about 31.2¢. It is the difference between 7/5 and 11/8 as well as the difference between 7/4 and 55/32. When used as an interval in its own right, 56/55 acts as a sort of small "unind"- a type cross between a unison and a second.
