The Tarot equivalence continuum is a continuum of 2.3.5 subgroup temperaments which all equate a number of [[22nd-octave temperaments#Major Arcana|Major Arcana]] commas with the [[barium]] comma, which due to it being period-56 can also be called Minor Arcana comma. Since there's 22 cards in the Major Arcana, and 56 in the Minor Arcana, the natural name that arises is Tarot equivalence continuum. | The Tarot equivalence continuum is a continuum of 2.3.5 subgroup temperaments which all equate a number of [[22nd-octave temperaments#Major Arcana|Major Arcana]] commas with the [[barium]] comma, which due to it being period-56 can also be called Minor Arcana comma.

All temperaments in this continuum satisfy (2<sup> | All temperaments in this continuum satisfy {{nowrap|(2<sup>−193</sup> 3<sup>154</sup> 5<sup>−22</sup>)<sup>''n''</sup> ~ (2<sup>−225</sup> 3<sup>224</sup> 5<sup>−56</sup>)}}. If we allow non-integer and infinite ''n'', the continuum describes the set of all 5-limit temperaments supported by [[1848edo]], due to it being the unique equal temperament that tempers both commas and thus tempers all combinations of them. The just value of n is approximately 2.0070839..., and temperaments having ''n'' near this value tend to be the most accurate ones. | ||
The continuum contains two notable 5-limit temperaments supported by 1848edo, minortone and atomic. | The continuum contains two notable 5-limit temperaments supported by 1848edo, minortone and atomic. | ||
