The last is the cube of a 6-et comma, 2 (49/55)^6 = .12 cents, so this
can be regarded as a matter of putting the 9-et with the 6-et and getting
18. Instead of a 1/18 symbol, I suppose we could have a whole-tone
symbol, as this comma tells us the 12-et whole tone, or 200 cents, is
almost exactly 55/49 = 9/8 440/441 (199.98 cents.)
