Because the generator is so close to 1/3 of an octave, and the interval left over is accordingly so small, all small magic mos scales consist of three large intervals alternating with three groups of this small interval. Specifically, there are the following scales, where s always represents the characteristic small interval, which simultaneously represents [[128/125]], [[36/35]], [[28/27]], and [[25/24]].
* [[3L 4s]]: LsLsLss, where L represents 6/5
* [[3L 7s]]: LssLssLsss, where L represents 7/6
* [[3L 10s]]: LsssLsssLssss, where L represents 9/8
* [[3L 13s]]: LssssLssssLsssss, where L is a neutral second, which can be taken to represent [[12/11]]~[[13/12]] (in magic temperament) or [[11/10]] (in the related [[telepathy]] temperament). In 22edo they are identical.
