All temperaments in the continuum also satisfy (15625/15552)<sup>''s''</sup> ~ 20000/19683, for a value of ''s'' defined such that 1/''r'' + 1/''s'' = 1; equivalently, we can offset ''s'' by 1, and equate a number of [[15625/15552|kleismas (15625/15552)]] with the diaschisma, giving rise to the name ''diaschismic-kleismic equivalence continuum''. Varying ''s'' results in different temperaments listed in the table below. It converges to [[hanson]] as ''s'' approaches infinity, and is motivated by the fact that many important temperaments of 34edo follow a chain of commas connected by kleismas. The just value of ''s'' is 3.4117…, and temperaments near this tend to be the most accurate.
All temperaments in the continuum also satisfy (15625/15552)<sup>''k''</sup> ~ 20000/19683, for a value of ''k'' defined such that 1/''r'' + 1/''k'' = 1. Varying ''k'' (for <sup>(number of)</sup> ''k''leismas) results in different temperaments listed in the table below. It converges to [[hanson]] as ''k'' approaches infinity, and is motivated by the fact that many important temperaments of 34edo follow a chain of commas connected by kleismas as discovered by [[User:Lériendil|Lériendil]]. The just value of ''k'' is 3.4117…, and temperaments near this tend to be the most accurate.
