99/98, or the mothwellsma (17.6 cents in size), represents the difference between the 9/7 and 14/11 supermajor thirds, or the difference between two 7/6 subminor thirds and one 11/8 semi-augmented fourth. If tempered, it leads to the Mothwellsmic triad, and is related to 11-limit orwell, as a generator between 7/6 and (11/8)^1/2 – is befitting of orwell.

(Note that (11/8)^1/2 = 7/6 × (99/98)^1/2 and that 7/6 × 99/98 = 33/28, which is the fifth complement of 14/11.)
