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, but have the basic tuning as 17edo/17ed4's fifth instead of 12edo's fifth. They are also more widely spaced than diatonic scales, comparable more to an octave-period pentatonic scale.
