Equal tunings
This MOS pattern is somewhat of a wasteland as far as low-harmonic-entropy scales are concerned. However, there is one interesting no-5's scale, bleu. In this scale, 5 steps make a 3/2, and the chord 11:12:13:14 is represented as three equal steps.
In 33edo and 41edo, one short step of this scale is close to the one step of Bohlen-Pierce, or bohpier, octave temperament which has a relationship with BP. The 33edo scale is notable outside of music in that this scale is a leap year pattern of the tabular Iranian calendar, where the leap year is inserted 7 times once in 4 years, with 1 gap of 5 years.
