Here's some info about lemba temperament:

Lemba has a septimal whole-tone generator 8:7 that divides the perfect fifth 3:2 into 3 equal parts, so it's similar to mothra temperament.
However, it has a half-octave period, so the stacked generators are not reduced by the octave, but by the tritone (7:5 or 10:7). The major third 5:4 is generated by reducing the tritone 10:7 by a septimal whole-tone 8:7.

In 16-edo, the septimal whole-tone is 3 steps, and the tritone is 8 steps. Lemba[10] (the scale in the video) can be generated by stacking 2 generators up and down within the first tritone (-> 0 2 3 5 6 8), and repeating the pattern for the second tritone (-> 0 2 3 5 6 8 10 11 13 14 16). Or, in single steps: 2 1 2 1 2 2 1 2 1 2.

An advantage of such a half-octave period is that you can tune the strings in tritones, and the scale pattern is identical for each string. ^^

Another tuning that supports lemba is 26-edo; here, the pattern is as following:
degrees: 0 3 5 8 10 13 16 18 21 23 26
steps: 3 2 3 2 3 3 2 3 2 3
