The sparkisma, with a ratio of 14400/14399, is an unnoticeable 17-limit superparticular comma that separates the lynchisma (120/119) and the biyatisma (121/120), as well as the amount by which a stack consisting of 7/4, 121/64 and 17/16 falls short of 225/128, the Neapolitan augmented sixth, upon octave reduction. It is also equal to the difference between (99/70)/(11/10)3 = 900/847 and 17/16, so because of the relation to stacking 11/10's and to the half-octave interval 99/70 one may want to temper 9801/9800 too (and possibly also S10/S11 if you want to equate (11/10)3 with 4/3). Tempering this out in the full 17-limit results in the sparkismic temperament, or in the 2.3.5.7.11.17 subgroup, the spark temperament.
