2L 3s⟨3/2⟩ can be interpreted as the [[nonoctave]] [[regular temperament]] named [[subgroup temperaments#pythium|pythium]] by [[User:CompactStar]], tempering out [[81/80]] in the 3/2.4.5 subgroup. This is the simplest 3/2-equivalent temperament not containing octaves. Because the 3/2-reduced 5th harmonic of [[40/27]] is conflated with the just perfect fifth, the CTE generator of this temperament is exactly the [[32/27]] Pythagorean minor third. Although the most accurate tunings use near-32/27 generators, pythium can be tuned with minor thirds as sharp as that of [[11edf]]'s (319 cents). The best extension of pythium to the 3/2.4.5.7 subgroup adds [[64/63]] to the comma list, making the CTE generator slightly flatter than 32/27, near [[22edf]]'s minor third of 287 cents.
