Gene Ward Smith had had commented on the tuning list on 10 April 2006:

<Any otonal chord can be considered a utonal chord, and vice-versa … 1-11/9-3/2-11/6. The inverted chord is 1-9/11-2/3-6/11, and upon multiplication by 11/6 that becomes 1-11/9-3/2-11/6 again. Have these been considered and given a name? If not, “outonal chord” is my proposal.>

I had had then suggested the term “ubi-tonal” for suchlike chords.
