This is the MOS where the large steps divide the small steps into groups of 3-3-3-3-3-4. It is generated by a "neutral" whole tone of no less than 4/25edo (192{{c}}), laying estimates of the boundary of "practicality" between [[37edo]] (minimum) and [[43edo]] (maximum).
This is the MOS where the large steps divide the small steps into groups of 3-3-3-3-3-4. It is generated by a "neutral" whole tone of no less than [[25edo|4\25]] (192{{c}}), which is most commonly taken to represent [[28/25]] and [[19/17]]; interpreting it as [[Didacus]][25], 2 generators reach [[5/4]] and 5 generators reach [[7/4]]. Various extensions of didacus exist to find the 3rd harmonic within the MOS, most prominently [[hemithirds]] (-15 generators) and [[hemiwürschmidt]] (+16).
