7L 3s<4/1> refers to a non-octave MOS scale with a period of a 4/1 and which has 7 large and 3 small steps. These scales are in some ways similar to diatonic scales because they are generated from perfect fifths and have the 7edo/7ed4 685-cent flat fifth and 5edo/10ed4's 720-cent sharp fifth at the ends of the tuning spectrum. However, equalized and collapsed tunings are now swapped (equalized is 720-cent fifth and collapsed is 685-cent fifth is equalized), and the basic tuning is now the 705-cent gentle fifth from 17edo/17ed4 instead of 12edo's fifth. These scales are also more widely spaced than diatonic scales, comparable more to an octave-period pentatonic scale.
