Various 22edo triads, 6th and 7th chords, named via ups and downs. Not meant to be exhaustive, but this list does demonstrate the basic rules for naming.

m3 ^m3 vM3 M3 P4
triad Cm C^m Cv C C4
vM6 Cmv6 C^mv6 Cv6 C,v6 C4v6
M6 Cm6 C^m,6 Cv,6 C6 C4,6
m7 Cm7 C^m,7 Cv,7 C7 C4,7
^m7 Cm^7 C^m7 Cv^7 C,^7 C4^7
vM7 CmvM7 C^mvM7 CvM7 C,vM7 C4vM7
M7 CmM7 C^mM7 Cv,M7 CM7 C4M7

A comma (the actual punctuation mark ",") is spoken as "add", thus Cv,7 is "C-down add-seven". The only exception is when a comma separates two numbers, as in C4,7 which is "C four-seven". A comma is written, and "add" is spoken, whenever not doing so would cause confusion with another chord.

4:5:6:7 = C vE G Bb is named Cv,7. To get a shorter name for this important chord, one could call it a harmonic7 chord, or one could borrow from color notation to call it a har7 chord, written Ch7. Names for subharmonic chords can be similarly shortened.
