=== 77edo (demonstrated to work) ===

[[Bryan Deister]] has demonstrated a [[7L 2s]] mapping for [[77edo]] in [https://www.youtube.com/shorts/wSZez2KgP2U ''microtonal improvisation in 77edo''] (2025). [[Tsaharuk]] is a member of the [[Schismatic family]] that splits the (highly accurate) fifth (~[[3/2]], as 45\77) into five parts (9\77), which function as lesser tridecimal neutral seconds ~[[13/12]]. Two of them (18\77) make a flat minor third ~[[20/17]]; three of them (27\77) make a sharp major third ~[[14/11]]; and four of them make a near-just tridecimal augmented fourth ~[[18/13]], which serves as the dark generator for the 7L 2s scale in the manner of Mavila, but since it is not mapped as a fourth, it can be stacked to get an actual near-just fourth or fifth (depending upon direction of stacking), needing ten to do so, as in [[Mabila family|Mabila]]. The overall range is approximately three and a half octaves (which slope upwards mildly), but each octave is missing a few notes.
