54:64:81, is a minor triad found on the ii, iii, and vi of the 3-limit diatonic scale.

In meantone this chord is tempered together with both 10:12:15 and 27:32:40, so it may be considered a 3-limit approximation of those chords, or a chord in its own right with a less-stable third. Unlike 10:12:15, 54:64:81 is ambitonal.
